Python row major to column major order vector

Question

Having a matrix like

ma = [[0.343, 0.351, 0.306], [0.145, 0.368, 0.487]]

I want to get a vector like:

[0.343, 0.145, 0.351,         


        

Answer 1

Flatten the array in Fortran order:

c = a.flatten(order='F')

You could also get the results you wanted with reshape, but it's wordier:

c = a.reshape(a.size, order='F')
