Hey I wrote:
X=linspace (0,1,8)
Y=A (13:20,2)
(I had "A" form my last program)
P=polyfit (X,Y,7)
And it says error using polyfit X and Y vectors must be the same size! But they are same sized!!!I don't know what's wrong with it!

They have the same number of elements, but they are not the same shape. You need to transpose one of them.

P=polyfit(X,Y.',7)
FYI, you could have found this by trying
docsearch transpose
