MATLAB: Arrays

arraysvectors

I have 'n' number of column vectors of size 3000.

I want to put these 'n' column vectors in a matrix like this

X = [n1 n2 n3 …];

Any help is appreciated. Thanks

Edit I have an image matrix converted to vector. I have around 300 Image vectors now. I have to make a complete array with having all those 300 vectors. In that matrix there should be 1 column of each image vector. here n1 is my first image vector, n2 is second image vector and so on.
