(X',Y') in Matlab

I wanted to know what is the codes: [U,T] = regression(A',B') means in matlab, I know that A' means transpose but as A is a vector I can not understand how it works here.

You can certainly transpose a vector. The transpose of a row vector is a column vector, for example.

Yes that is correct but then the regression gives a matrix as the result. I need just one result for each answer of regression not a matrix.

I was simply pointing out how the transpose of a vector is defined.

Keep the vector as a row or column vector, depending on what your code requires. You may have to experiment with it (either as a row or column vector) to get the result you want.

If you want to be sure that ‘A’ is always a column vector, refer to it in the argument list as: A(:). If you want it to always be a row vector, refer to it as: A(:)'. That way, you never have to worry about what it is in your code.
