Modify last column in a matrix, replacing with an equally spaced range of values?

I'm generating a 42*42 matrix, T, of temperature values. Most interior values are 10 (initial guess for iteration purposes). Row 1 is all 4's, row 42 all -17. I need to make the final column (42) a range of equally spaced values from 4 to -17. What's the best way to do this?

Below is how I'm doing this so far (forgive me, I'm VERY new at this):

T=10*ones(42,42);

T(1,1:end)=4;

T(42,1:end)=-17;

I don't know how to handle the final column simply? I can change the full column with

T(:,end)=new_value

So I've been trying variations on that, say with a range on the right hand side:

T(:,end)=4:-17

But I can't make it work and I'm not having much luck in the help files.

Can anyone set me straight please?

T(:,42) = linspace(4,-17,42)'

Perfect!

Just what I needed, thanks ever so much.
