QGECO_TEST QGECO factors a general matrix and computes its reciprocal condition number; QGESL can be called afterwards to solve a factored linear system. The matrix size is N = 3 Factor the matrix. The reciprocal matrix condition number = 0.246445E-01 Solve the linear system. Solution returned by QGESL (Should be (1,2,3)) 1.00000 2.00000 3.00000 Call QGESL for a new right hand side for the same, factored matrix. Solve a linear system. Solution returned by QGESL (should be (1,0,0)) 1.00000 0.00000 0.00000 Call QGESL for transposed problem. Call QGESL to solve a transposed linear system. Solution returned by QGESL (should be (-1,0,1)) -1.00000 -0.342388E-33 1.00000 QGEDI_TEST QGEDI computes the inverse and determinant of a matrix factored by QGEFA. The matrix size is N = 3 Factor the matrix Get the inverse and determinant The determinant = 2.70000 * 10 ** 1.00000 The inverse matrix: -1.77778 0.888889 -0.111111 1.55556 -0.777778 0.222222 -0.111111 0.222222 -0.111111 QGEFA_TEST QGEFA factors a general matrix, which can then be solved by QGESL. The number of equations is N = 3 The matrix A: 1.00000 2.00000 3.00000 4.00000 5.00000 6.00000 7.00000 8.00000 0.00000 The right hand side B is 14.0000 32.0000 23.0000 Factor the matrix Solve the linear system. QGESL returns the solution: (Should be (1,2,3)) 1.00000 2.00000 3.00000 QGESL_TEST QGESL solves a factored linear system after it has been factored by QGEFA. The matrix size is N = 100 Factor the matrix. Solve the linear system. The first and last five solution entries: (All of them should be 1.) 1 1.00000 2 1.00000 3 1.00000 4 1.00000 5 1.00000 ...... .............. 96 1.00000 97 1.00000 98 1.00000 99 1.00000 100 1.00000 LINPACK_Q_PRB Normal end of execution. 15 March 2016 8:10:42.641 PM
