d = size(X)[m n] = size(X)m = size(X,1)n = size(X,2)
d = size(X), where X is an m-by-n matrix, returns a vector with two integer components, d =
[m n] = size(X) size returns the two integers in two separate variables.
With a second input argument
m = size(X,1) returns the row size of X.
n = size(X,2) returns the column size of X.
