I have an old fortran application which uses a sparse linear solver called "hsl ma37" which receives the data in coordinate system. The easiness of inputing the data is that you can add them in any order i.e. you can have (1,2,1) and (1,2,3) and the solver will take care to add them and make (1,2,4).

I want to use the mkl_dcsrcoo to convert the matrix to csr form in order to try some newer solvers before I restructure the program to save in csr form.

So here comes my question: Will the procedure take care of the duplicate entries?

Thanks in advance,

Petros

The converter doesn't take care of the duplicate entries. In your case, two entries (1,2,1) and (1, 2,3) will exist in the CSR representation.

All the best
