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
