Merge two colums into one

Hi, I´m an absolutly matlab greenhorn. I hope its okay, if i ask some "maybe" stupid questions.

I have an array (6x2), in my example are these colums A and B, and I need an array (6x1) ... colum C.

How can I merge these two colums A and B to colum C?

Thanks for your help.

Best Regards

Assuming that X is your matrix:

C        = X(:, 2);
match    = isnan(C);
C(match) = X(match, 1);
