Returns the size of a variable. There are two syntaxes for its use. The first syntax returns the size of the array as a vector of integers, one integer for each dimension
[d1,d2,...,dn] = size(x)
The other format returns the size of x along a particular
dimension:
d = size(x,n)
where n is the dimension along which to return the size.
--> a = randn(23,12,5);
--> size(a)
ans =
<uint32> - size: [1 3]
Columns 1 to 3
23 12 5
Here is an example of the second form of size.
--> size(a,2)
ans =
<uint32> - size: [1 1]
12
