MATLAB size Function: Get Array Dimensions

The 'size' function in MATLAB returns the number of rows and columns of a matrix or array. The syntax is as follows:

'size(A)'

where 'A' is the name of the matrix or array.

For example, if we have a matrix 'A' with dimensions 3x4, the 'size' function will return:

A = [1 2 3 4; 5 6 7 8; 9 10 11 12]; size(A) ans = 3 4

This indicates that the matrix 'A' has 3 rows and 4 columns.
