how do i turn an array into a column vector?

I can't work out how to change my array into a column vector. I thought it was just putting ' after it, but that's not working. If I had A=[1,2,3,4] how would I make that into a 4x1 column vector?

[Jan]

For "A = [1,2,3,4]" inserting a ' afterwards is sufficient:

A = [1,2,3,4]'

or:

A = [1,2,3,4]; disp(A');

If this does not work for your code, please post the code and the error message.

For any kind of array you get a single column vector by

A(:)

Or if you are sure that A is a row vector,

A.'

Caution: A' is the conjugate transpose and the plain transpose is A.'
