Any idea how to vary the filename in this command to produce different movie-files instead of overwrite one file? How are we doing? Please help us improve Stack Overflow.

A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns.

Even a single number is stored as a matrix. For example, a variable containing the value is stored as a 1-by-1 matrix of type double. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements. The size of the resulting matrix is 1-by-4, since it has one row and four columns.

A matrix of this shape is often referred to as a row vector. Now create a matrix with the same numbers, but arrange them in two rows. This matrix has two rows and two columns. For example, the zeros and ones functions create matrices of all zeros or all ones.

The first and second arguments of these functions are the number of rows and number of columns of the matrix, respectively. The diag function places the input elements on the diagonal of a matrix. For example, create a row vector A containing four elements. Then, create a 4-by-4 matrix whose diagonal elements are the elements of A. You can also use square brackets to join existing matrices together. This way of creating a matrix is called concatenation.

For example, concatenate two row vectors to make an even longer row vector. To arrange A and B as two rows of a matrix, use the semicolon. To concatenate two matrices, they must have compatible sizes. In other words, when you concatenate matrices horizontally, they must have the same number of rows.

When you concatenate them vertically, they must have the same number of columns. For example, horizontally concatenate two matrices that both have two rows. An alternative way to concatenate matrices is to use concatenation functions such as horzcatwhich horizontally concatenates two compatible input matrices. The colon is a handy way to create matrices whose elements are sequential and evenly spaced.

For example, create a row vector whose elements are the integers from 1 to By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. The dark mode beta is finally here.

Matrices in MATLAB are automatically grown and padded with zeroes when you assign to indices outside the current bounds of the matrix. For example:. I have edited my earlier solution so that you won't have to supply a maxLength parameter to the function.

The function calculates it before doing the padding. The convenience of having it as a function is that you can easily join multiple uneven vectors in a single line as joinUnevenVectors vec1,vec2,vec3,vec4 and so on, without having to manually enter it in each line.

Matlab automatically does padding when writing to a non-existent element of a matrix. Therefore, another very simple way of doing this is the following:. Learn more. Asked 8 years, 10 months ago.

Would work, but was looking for a function that would not force the usage of the maxLength param.Documentation Help Center. You can use the square bracket operator [] to concatenate. Create two 3-D arrays and concatenate them along the third dimension. The lengths of the first and second dimensions in the resulting array matches the corresponding lengths in the input arrays, while the third dimension expands.

Concatenate a date character vector, a string date, and a datetime into a single column of dates. The result is a datetime vector. Create a cell array containing two matrices, and concatenate the matrices both vertically and horizontally.

Dimension to operate along, specified as a positive integer scalar. For example, if A and B are both 2-by-2 matrices, then cat 1,A,B concatenates vertically creating a 4-by-2 matrix.

First input, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. Second input, specified as a scalar, vector, matrix, multidimensional array, table, or timetable.

The elements of B are concatenated to the end of the first input along the operating dimension. The sizes of the input arguments must be compatible. For example, if the first input is a matrix of size 3-by-2, then B must have 2 columns to concatenate vertically, and 3 rows to concatenate horizontally. When concatenating horizontally, all table inputs must have unique variable names. When present, row names must be identical, except for order.

Similarly, all timetable inputs must have the same row times and all columns must have different names. You can concatenate valid combinations of different types. For more information, see Valid Combinations of Unlike Classes. List of inputs, specified as a comma-separated list of arrays to concatenate in the order they are specified. The inputs must have compatible sizes. For example, if A1 is a row vector of length mthen the remaining inputs must each have m columns to concatenate vertically.

To construct text by horizontally concatenating strings, character vectors, or cell arrays of character vectors, use the strcat function. To construct a single piece of delimited text from a cell array of character vectors or a string array, use the strjoin function. When concatenating an empty array to a nonempty array, cat omits the empty array in the output. For example, cat 2,[1 2],[] returns the row vector [1 2].Documentation Help Center.

The colon is a handy way to create matrices whose elements are sequential and evenly spaced. For example, create a row vector whose elements are the integers from 1 to You can use the colon operator to create a sequence of numbers within any range, incremented by one.

To change the value of the sequence increment, specify the increment value in between the starting and ending range values, separated by colons. You can also increment by noninteger values. If an increment value does not evenly partition the specified range, MATLAB automatically ends the sequence at the last value it can reach before exceeding the range.

You can add one or more elements to a matrix by placing them outside of the existing row and column index boundaries.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I would like to create a 10 bit binary value by concatenating two 4-bit value and one 2-bit value.

Note: On most PC, binary ordering is "lower endian". Depending on the endianness, you may want to "flip" your bit array before converting it, which can be done with fliplr :.

Matlab doesn't let you process types that are not really supported in that way or if you really want to do it in Matlab it will be very ugly and slow. Learn more.

Each input argument can be a character array, a cell array of character vectors, or a string array. If any input is a cell array, and none are string arrays, then the result is a cell array of character vectors.

For character array inputs, strcat removes trailing ASCII white-space characters: space, tab, vertical tab, newline, carriage return, and form feed. For cell and string array inputs, strcat does not remove trailing white space.

Starting in Ra, you can create string arrays using double quotes. Concatenate them with the strcat function. Input text, specified as character arrays, cell arrays of character vectors, or string arrays. When combining string or cell arrays with character arrays, the string or cell arrays must be either scalars or column vectors with the same number of rows as the character arrays. Data Types: char cell string. Character arrays also can be concatenated using left and right square brackets.
