least square fit.

Hi, Please I need help solving and plotting this regression in matrix form using Matlab. Thanks a lot

[Abraham Kaz]

I understand how to set it up in a matrix form on paper but I'm new to Matlab and I have to use Matlab to compute it. Thanks

v=A\z

[Abraham Kaz]

This is a least square fit problem. I know V = (A*T*A)^-1 A*T*Z. I need help with doing this on Matlab. You wrote V = A/Z. That does not do anything sir

[Matt J]

No, I wrote v=A\z. It will do exactly what you request.

[Abraham Kaz]

How do I do that in Matlab. Could you please provide more details. Thanks

At the command prompt, simply enter v=A\z
