Hello,
I am having a problem solving an overdetermined system of equations.
Specifically, I have 180 equations in 5 variables. Each of these
equations takes the form
C1*H1 + C2*H2 + C3*H3 + C4*H4 + C5*H5 = L
where the h's are the unknowns and all of the values for C1...C5 and L
are known. Currently, I have values for the C's and L which are
calculated form specific values of the H's. I have tried
FindRoot,Solve and Nsolve and only met with different error messages.
FindRoot does not like overdetermined systems and both Solve and Nsolve
cannot seem to get going even when specifying two starting values for
the secant method. If anyone could point me in the right direction on
this, I would be most appreciarive.
Thank you,
Mark Storch
