If you want to create normally-distributed random variables with a standard deviation of s and a mean of m with randn, this will work:
nrmrnd = @(m,s) m + s*randn;
or if you want a row r by column c matrix of them:
nrmrnd = @(m,s,r,c) m + s*randn(r,c);

This function should work:
xrndn = @(x) randn(length(x))*x(:);
Call it as:
y = xrndn(x);
for any vector x.
