| 3 | % This is because Matlab defines A ./ B to be the matrix with |
---|
| 4 | % elements A(i, j)/B(i, j) and A .\ B to be the matrix with elements |
---|
| 5 | % B(i, j)/A(i, j). This is not consistent with the ideas of left |
---|
| 6 | % and right division in a non-commutative algebra, therefore it is |
---|
| 7 | % not supported for quaternion arrays. The operator ./ implements |
---|
| 8 | % elementwise division on the right, as expected, but to obtain |
---|
| 9 | % elementwise division on the left use: inv(B) .* A |
