Linsolve_params

-- Option variable: linsolve_params Default value: true

When linsolve_params is true, linsolve also generates the %r symbols used to represent arbitrary parameters described in the manual under algsys. Otherwise, linsolve solves an under-determined system of equations with some variables expressed in terms of others.

linsolve_params:true;
h[i,j]:=random(5)+1;
A:genmatrix(h,2,3);
d:[3*A[1][1]+A[2][1],3*A[1][2]+A[2][2],3*A[1][3]+A[2][3]];
D:addrow(A,d);
X:[x,y,z];
for m:1 thru 2 do(b[m]:random(5)+1,b:[b[1],b[2],3*b[1]+b[2]]);
b;
C:(D.X);

(%o1)                                true
