Hi everyone,
I would like to center a vector A = randn(50,1) to center, meaning that (1/N)*sum(a(i)) = 0 , where a is the centered vector A, i = 1, .. ,50 and n=50. Moreover, if I have a matrix B = randn(50,4) how could we standardize it, meaning that (1/n)*sum(x(i))=0 and (1/n)*sum(x^2)=1, namely they follow a normal distribution with zero mean and unit variance N(0,1). Could anyone help with these two problems?
