I ran your code through the NAG Fortran Compiler (on Linux). The version you have posted doesn’t compile for me:<\/p>\n

> nagfor -mtrace=all -u -C=all -C=undefined valuefuncmat.f90\n...\nError: valuefuncmat.f90, line 100: Syntax error\n       detected at )@,\n...\n<\/code><\/pre>\n
That of course is easy to rectify (i.e., change line 100 to write(*,'(20G12.4)') vOUT(i,:)<\/code>).<\/p>\n
With that done, recompiling and running reveals<\/p>\n
