PETSc exercises

1_petsc_hello

Try to create a simple "hello world" using the most simple PETSc directives.
Compile it with the makefile provided and make it run!

2_petsc_vec

Starting with the source code provided try to use properly the PETSc vectors:
- Duplicate a vector
- Create a vector
- Set some vector values (remember VecAssemblyXXX() calls!)
- Try some numerical operations

You can use as input data the files linked below:

va_200.bin   vb_200.bin

3_petsc_mat
Starting with the source code provided try to use properly the PETSc matrices:
- Duplicate a matrix
- Create a matrix
- Set some matrix values (remember MatAssemblyXXX() calls!)
- Try some numerical operations

You can use as input data the files linked below:

mA_300x200.bin   mB_300x200.bin   mC_200x200.bin
