For example when setting a single value in a matrix with MatSetValues() 2104 you cannot have something like 2105 $ PetscInt row,col 2106 $ PetscScalar val 2107 $ ... 2108 $ call MatSetValues(mat,1,row,1,col,val,INSERT_VALUES,ierr) 2109 You must instead have 2110 $ PetscInt row(1),col(1) 2111 $ PetscScalar val(1) 2112 $ ... 2113 $ call MatSetValues(mat,1,row,1,col,val,INSERT_VALUES,ierr) 2114 2115 2116 See the example src/vec/vec/examples/tutorials/ex20f90.F90 for an example that can use all four approaches 2117 2118 Developer Notes: The finclude/petscXXXdef.h contain all the #defines (would be typedefs in C code) these 2119 automatically include their predecessors; for example finclude/petscvecdef.h includes finclude/petscisdef.h 2120 2121 The finclude/petscXXXX.h contain all the parameter statements for that package.
