I am using the following sequence of commands to write a Vec b to a binary file
and then eventually read it in MATLAB, but I get an error when I try writing
this vector to a file in PETSc.
ierr = PetscViewerBinaryOpen(PETSC_COMM_WORLD, filesol, FILE_MODE_WRITE,
&binviewersol) ; CHKERRQ(ierr) ;
ierr = PetscViewerBinaryGetDescriptor(binviewersol, &fd); CHKERRQ(ierr) ;
ierr = PetscBinaryWrite(fd, b, 5, PETSC_SCALAR, PETSC_FALSE); CHKERRQ(ierr) ;
Here is the error :
[1]PETSC ERROR: Write to file failed!
[1]PETSC ERROR: Error writing to file.!
NOTE : Petsc is configured with complex option and Vec b has complex entries.
Length of Vec b is 5 .
