Hello;
I've a number of sets of simultameous linear equations, with the number of
unknowns and no. of equations are equal in each set.
All the coefficients are to be read from a w/s. The values of the unknowns
are to be posted in a different w/s in the same w/b.
The number of unknowns in each set is less than 10. (In other words, not in
the 100s or the 1000s)
1. I'm a bit surprised that such relatively simple math. tool is not
included as a built=in feature in the Excel Analysis Tool. or, is it ?
2. It is likely that several VBA macros (w/code) do exist, but I've tried
100s of web sites and could not find what I'm looking for!
Could you please advise or refer me to a particular site ?
3. Alternatively, I do have a well-commented and very reliable (LU
Decomposition) FORTRAN Subroutine code (about 40 relatively simple
statements) that could possibly be converted (with your help!) to a VBA macro
for use in Excel (2003 Win XP).
I would very much appreciate your suggestion(s).
Thank you kindly.
(PS. I've already solved couple of sets manually, which could be used later
to validate the macro)
