C++ solving set of linear equations

Hey there,

Have a look on the net for Numerical Recipe's in C++, chapter 2 on matrix functions, specifically different methods of solving linear equations.... Its a book really worth buying (will save you days of heartbreak) and comes with the c++ implementations of all their algorithms.

Cheers

The Excel spreadsheet has the functions Minverse & Mmult that are used to solve sets of equations. The help function will lead you in setting up the coefficient array & inverting it (be sure to designate the array as an "array function" as explained in help). Then multiply the inverted array by the single col array containing the factors equal to the equations. This will produce the solution to all the unknowns & put in another array. Try this with a simple 2X2 matrix of two equations with known values. When this works scale it up to your problem. Sounds difficult but by following the help functions & possibibly assistance from a spreadsheet pro, this will do the trick - Good Luck.
