Hi sirs,
I am trying to convert a matrix into a single vector through the syntax ":" or "reshape", but they do not work as I want. They work column by column, but I want row by row, like this:
Is there any way to do this?
Thank you very very for the reply. All the best.

In order to achieve this, you can first take the transpose of the matrix and then apply reshape method on it.
Lets say a = [1 2; 3 4]
b = a'
vec = b(:)
