how to solve a equation set automatically in IDL? [message #66693]

Hi, there

I wonder whether there is some automatic method / function in IDL to
solve an equation set.

Supposing that I got an equation like: A*x+B*y+C*z=E*m+F*n , and
I got five sample points (xi,yi,zi,mi,ni), (1<= i <=5). well, I can
solve the equation set (including 5 equations) mathematically and got
value for parameter A,B,C,D,E.

How can I do it automatically without listing the expressions like A=f
(x,y,z,m,n), B=f(x,y,z,m,n), C=f(x,y,z,m,n)...?

Thanks
