hi! i have an array A of size (75*1). i want to generate from this array a big Matrix of size(75*75* 30) i did it in this manner
M_m=bsxfun(@plus,A,10*rand([1 3],75,30))
my problem i want to mhave not only plus but also minus. something lik this:
M_m=bsxfun(@plus,A,10*rand([1 3],75,30)*sign(randn(75,30)))
could someone help me?

75 by 75 by 30 is far from big. But anyway, it seems like you want to add noise to some 3D array but I'm not sure what pattern you're going to use to build that 3D array from the column vector that is A. Please clarify.
