inlinestatic

Returns entry (i, j) of the matrix product \( e_1 \cdot e_2 \).

Template Parameters

E1	The first matrix expression type.
E2	The second matrix expression type.

Parameters

e1	The first matrix expression.
e2	The second matrix expression.
i	The zero-based row index of the result entry.
j	The zero-based column index of the result entry.

Returns

\( \sum_k e_1(i, k) \cdot e_2(k, j) \).

Exceptions

Base::SizeError

if e1.getSize2() does not equal e2.getSize1().
