What is the correct Syntax for accessing more than 3 variables in CFTOOL in Custom Equation Section ?

I have 5 variables a,b,c,d,e and I made a matrix called x=[a b c d] and y=[e]

Now using cftool I want a relation called (y=p.*x(a)+q.*x(b)+r.*x(c)+s.*x(d))

I want to find p,q,r,s

 and  do not want to do by x\y method

cftool did not change since yesterday. If you couldn't then, then you can't today.

Did you try Generalized Linear Models?

They should allow you to handle more than the two dimension limit of cftool.
