I hope this is not too much of a beginner's question, I just started using sparse matrices with MKL a few days ago. This is work within a large codebase so working examples are very time consuming to create. I will try to ask my question without any code snippet. Here goes:
I am using d/zcsrcoo to convert from COO to CSR, for square matrices ~10k-~100k, and it seems that everything is okay.
However, I need to convert also rectangular sparse matrices with the same number of rows, but the number of columns easily x2~4.
