September 29 2010 12:22:42.354 PM TRIANGLE_EXACTNESS FORTRAN90 version Investigate the polynomial exactness of a quadrature rule for the triangle by integrating all monomials up to a given degree. The rule will be adjusted to the unit triangle. TRIANGLE_EXACTNESS: User input: Quadrature rule X file = "toms612_19_x.txt". Quadrature rule W file = "toms612_19_w.txt". Quadrature rule R file = "toms612_19_r.txt". Maximum total degree to check = 10 Spatial dimension = 2 Number of points = 19 Error Degree Exponents 0.0000000000000000 0 0 0 0.0000000000000000 1 1 0 0.0000000000000000 1 0 1 0.0000000000000002 2 2 0 0.0000000000000002 2 1 1 0.0000000000000002 2 0 2 0.0000000000000006 3 3 0 0.0000000000000004 3 2 1 0.0000000000000002 3 1 2 0.0000000000000004 3 0 3 0.0000000000000007 4 4 0 0.0000000000000002 4 3 1 0.0000000000000004 4 2 2 0.0000000000000002 4 1 3 0.0000000000000004 4 0 4 0.0000000000000004 5 5 0 0.0000000000000003 5 4 1 0.0000000000000002 5 3 2 0.0000000000000003 5 2 3 0.0000000000000002 5 1 4 0.0000000000000006 5 0 5 0.0000000000000008 6 6 0 0.0000000000000001 6 5 1 0.0000000000000003 6 4 2 0.0000000000000003 6 3 3 0.0000000000000003 6 2 4 0.0000000000000003 6 1 5 0.0000000000000008 6 0 6 0.0000000000000009 7 7 0 0.0000000000000002 7 6 1 0.0000000000000008 7 5 2 0.0000000000000006 7 4 3 0.0000000000000007 7 3 4 0.0000000000000010 7 2 5 0.0000000000000002 7 1 6 0.0000000000000009 7 0 7 0.0000000000000009 8 8 0 0.0000000000000002 8 7 1 0.0000000000000010 8 6 2 0.0000000000000007 8 5 3 0.0000000000000007 8 4 4 0.0000000000000008 8 3 5 0.0000000000000010 8 2 6 0.0000000000000002 8 1 7 0.0000000000000011 8 0 8 0.0000000000000017 9 9 0 0.0000000000000007 9 8 1 0.0000000000000009 9 7 2 0.0000000000000010 9 6 3 0.0000000000000008 9 5 4 0.0000000000000011 9 4 5 0.0000000000000011 9 3 6 0.0000000000000009 9 2 7 0.0000000000000004 9 1 8 0.0000000000000019 9 0 9 0.0000302640302663 10 10 0 0.0001513201513204 10 9 1 0.0006973206973210 10 8 2 0.0018813618813602 10 7 3 0.0033087633087645 10 6 4 0.0039770679770670 10 5 5 0.0033087633087648 10 4 6 0.0018813618813602 10 3 7 0.0006973206973210 10 2 8 0.0001513201513206 10 1 9 0.0000302640302664 10 0 10 TRIANGLE_EXACTNESS: Normal end of execution.
