How can I create a matrix of a size 50 x 50 in MATLAB and each column vector of matrix i.e., 50 x 1 size must have random numbers within a given range and then range for the next column vectors must decrement by k until last column vector is reached?
rand(50,50) will give you a matrix or random numbers between 0 and 1. Multiply it by row vector of ranges to get each column have the range corresponding to the value in row vector, e.g. rand(50,50).*(50:-1:1)
