impl. transpose matvec, matmul
t-hishinuma opened this issue · comments
I want to give modern and intuitive transposition information. But I have no idea how to implement it easily.
First, we create the following function as a prototype
matmul(A,B,C) // C=AB
matmul_TNN(A, B, C); // C=A^TB
matvec(A,x,y); // y = Ax
matvec_T(A, x, y); // y=A^Tx
This interface is not beautiful. However, it has the following advantages
- It does not affect other functions.
- Easy to trace with logger
- Simple to implement FFI in the future.
- When beautiful ideas appear in the future, these functions can be implemented wrapping it.
matmul_TNN(A, B, C); // C=A^TB
Transpose C is not implemented.
Therefore, change as follows.
matmul_TN(A, B, C); // C=A^T B^N
