Hi Dr. van Zon,

Just to be sure, for Assignment 6, are you looking for only one specific BLAS routine or could various choices be acceptable so long as it works and we explain it in enough detail in the code? Please let me know if you can and I would appreciate it.

Thank you

If your matrix has one or more special properties, and there is a BLAS routine for matrices with those properties, you should use it. In the assignment, the matrix does have special properties, and you should find the BLAS matrix-vector multiplication routine that is tailored to those properties. It is not enough if it just works, as the efficiency can vary a lot between the BLAS routines.
