It is supposed to generate a complex random number, and it worked on my friend's PC, but not mine.

out = crand(dim1,dim2)
Complex random matrix generator: generates a complex,
random matrix with a uniform distribution of dimension
DIM1 x DIM2. If only one dimension argument is given,
the output matrix is square.
See also crandn, rand, randn and sysrand.
But as Star Strider says, it's not in the MATLAB documentation
Star Strider's proposal is worth better than being deleted. Try this:
crand = @(m,n) randn(m,n) + 1i*randn(m,n);
C = crand(2,2)
Experiment to get different results, including with different random number generator functions
