- Dear nettors ,
- writing a program for a fortran77 project , i have run into a
- bad spot . the prg requires a matrix subroutine to calculate values for
- a set of equations . but the equations are not in a square matrix form .
- most books i have referred to give solutions to n x n matrices only .
- this prg of mine ,( to calcualte deflections of beams under different
- loading conditions) uses finite differentiaiton to get a set of
- equations . thus the equations are of the form
- k = x + y + z
-
- and so on giving me a n x 3 matrix . i am yet to find any concrete
- methods to solve such a system of equations . could anybody suggest
- something ?
-
- thanks
