Hello,

what code paths does `numpy.dot(matrix, matrix)` take with regard to the order 
of the input matrices (c/fortran contiguous?).

In particular, under what conditions does it make a copy of the input matrices, 
and under which conditions does it set the gemm transposition flags internally? 
Does this change with different numpy versions, is there a contract re this 
behaviour?

My concern is 1) memory (matrices are large, cannot afford extra copies) and 2) 
performance. 

Sorry if I missed this in the documentation. Cheers!
Radim
