All in all, I end up with this code:
module strassens_matmul
package {
T[][] mulIterative(T)(const T[][] mat1, const T[][] mat2) {
auto result = createMatrix!T(getRowSize!T(mat1),
getColumnSize!T(mat2));
foreach (row; 0 .. mat1.getRowSize()) {
foreach (column; 0 .. mat2.getColumnSize()) {
T value;
foreach (i; 0 .. mat1.getRowSize()) {
value += mat1.getPointCopy(row, i) *
mat2.getPointCopy(i, column);
}
*result.getPointPtr(row, column) = value;
}
}
return result;
}
}
Aren’t these passing by values? That’s why I used ref. Plus since
I don’t want to change the arrays in the function scope I used
const scope.
