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)'
