openblas sgemv CblasRowMajor implementation returns wrong results (cblas_sgemv)

Question

I did some test using cblas_sgemv in openblas and found that it returned a wrong result in my test case.

A is
1 2
3 4
5 6

B is 
1 2

The output C should be 5 11 17

But, it outputs 5 14 0

Here is the sample code. https://docs.google.com/document/d/15mCkfcQuruQxi4CjvVkoK2jfgnG2w3izd0wMFMW6UOk/edit?usp=sharing

Answer 1

the lda parameter seems to be wrong. since the order is CblasRowMajor it should be 2 (number of columns) instead of 3 (number of rows).
