how to convert a matrix into a vector

Hello all!

I have this matrix that is a size n x N and i would like to convert this matrix into a a vector of n*N x 1.

N = 401 and n = 5

so this is saying that every column has 5 dta points and I would like to have a column vector of the first column in the original matrix being the first set of rows in the new vector, the next column of the matrix be the next set of rows in vector etc.

Any help on automating this so I don't have to hard code a new column vector would be much appriciated!

Use the colon

a=rand(2,5)

a = 2×5

0.5636 0.5594 0.7487 0.8379 0.7064 0.0096 0.3643 0.6275 0.2889 0.1544

A = a(:)

A = 10×1

0.5636 0.0096 0.5594 0.3643 0.7487 0.6275 0.8379 0.2889 0.7064 0.1544
