BLAS clarifications

found the parameters lda, ldb and ldc very hard to interpret.
Fortunately, found this article: https://www.christophlassner.de/using-blas-from-c-with-row-major-data.html

that had a key sentence:

• Matrices $A$ and $B$, each followed by its leading dimension descriptor. This is the length of one row in row-major order, or the length of one column in column-major order,
• a scalar factor $\beta$ with which the elements of the matrix $C$ are multiplied, before its contents are added to the result of $\alpha \cdot {\text{op}}_A\left(A\right)\cdot {\text{op}}_B\left(B\right)$

thanks dude!
