D04AAF Example Program Results Four separate runs to calculate the first four odd order derivatives of FUN(X) = 0.5*exp(2.0*X-1.0) at X = 0.5. The exact results are 1, 4, 16 and 64 Input parameters common to all four runs XVAL = 0.5 NDER = -7 IFAIL = 0 with step length 0.5000 the results are Order Derivative Error estimate 1 0.1392E+04 -0.1073E+06 3 -0.3139E+04 -0.1438E+06 5 0.8762E+04 -0.2479E+06 7 -0.2475E+05 -0.4484E+06 with step length 0.0500 the results are Order Derivative Error estimate 1 0.1000E+01 0.1529E-10 3 0.4000E+01 0.2112E-08 5 0.1600E+02 0.3815E-06 7 0.6400E+02 0.7384E-04 with step length 0.0050 the results are Order Derivative Error estimate 1 0.1000E+01 0.1277E-13 3 0.4000E+01 0.4190E-09 5 0.1600E+02 0.1463E-04 7 0.6404E+02 0.2973E+00 with step length 0.0005 the results are Order Derivative Error estimate 1 0.1000E+01 0.1427E-12 3 0.4000E+01 0.3087E-06 5 0.1599E+02 0.6331E+00 7 0.3825E+05 -0.1964E+07
