hi! i usid bsx function to generate fro a vector a matrix by ading a random number. my problem: this function add to the whole vector a random number, but i want to add or substract to each number of the vector a random number. how could i manipulate this statement to generate the matrix?
MM is aknown vector M=bsxfun(@plus,MM,10*sign(randn([1 1],27,20)).*rand([1 6],27,20))

You could still use bsxfun, but instead of creating a vector of random numbers, if I understood correctly, you might need to create a matrix of random numbers to add it to the vector. Say MM is a column vector of size m1 and the random matrix is of size m1 x n1
m = 10; n = 25;
MM = randi(m,10,1); M = bsxfun(@plus,MM,randn(m,n));
