Symbolic matrix dimensions.
Syntax
d = size(A)
[m,n] = size(A)
d= size(A, n)
Description
Suppose A is an m-by-n symbolic or numeric matrix. The statement
d = size(A) returns a numeric vector with two integer components, d = [m,n].
The multiple assignment statement [m,n] = size(A) returns the two integers in two separate variables.
The statement d = size(A,n) returns the length of the dimension specified by the scalar n. For example, size(A,1) is the number of rows of A and size(A,2) is the number of columns of A.
Examples
The statements
syms a b c d
A = [a b c ; a b d; d c b; c b a];
d = size(A)
r = size(A, 2)
return
d =
4 3
r =
3
