Size of categorical array
d = size(A)
[m,n] = size(A)
[m1,m2,m3,...,mn] = size(A)
m = size(A,dim)
d = size(A) returns the two-element row vector d = [m,n] containing the number of rows and columns in the matrix for an m-by-n categorical matrix A. For n-D categorical arrays, size(A) returns a 1-by-n vector of dimension lengths. Trailing singleton dimensions are ignored.
[m,n] = size(A) for a categorical matrix A, returns the number of rows and columns in A as separate output variables.
[m1,m2,m3,...,mn] = size(A), for n>1, returns the sizes of the first n dimensions of the categorical array A. If the number of output arguments n does not equal ndims(A), then for:
| n > ndims(A) | size returns ones in the "extra" variables, i.e., outputs ndims(A)+1 through n. |
| n < ndims(A) | mn contains the product of the sizes of dimensions n through ndims(A). |
m = size(A,dim) returns the length of the dimension specified by the scalar dim. For example, size(A,1) returns the number of rows. If dim > ndims(A), m will be 1.
