Examples of com.nr.la.QRdcmp.solve()

com.nr.la.QRdcmp.solve()
Solve the set of n linear equations A*x = b. b[0..n-1] is input as the right-hand side vector, and x[0..n-1] is returned as the solution vector @param b @param x

      fail("*** QRdcmp: Matrix aqr.qt is not orthogonal");
      
    }


    ranvec(r);
    aqr.solve(r,y);
    localflag = maxel(vecsub(matmul(a,y),r)) > sbeps;
    globalflag = globalflag || localflag;
    if (localflag) {
      fail("*** QRdcmp: Error in solve() method");
