i have some equations on lagrange multipliers like...
-2a1-4a2+5a3+5a4-c+1=0
-4a1-8a2+10a3+10a4-c+1=0
5a1+10a2-13a3-14a4+c+1=0
5a1+10a2-14a3-17a4+c+1=0
a1+a2-a3-a4=0
where a1,a2,a3,a4 are lagrange multipliers
and c is a constant
i tried in matlab to find solution for these equation
but the matrix become nearly singular matrix.
please answer me how to find these a1,a2,a3,a4,c values...
