WebPlain matrices are used in special cases like setting up nonstandard camera projection. In Unity, several Transform , Camera , Material , Graphics and GL functions use Matrix4x4. Matrices in Unity are column major; i.e. the position of a transformation matrix is in the last column, and the first three columns contain x, y, and z-axes. WebBut the product's dimensions, when the matrices are multiplied in this order, will be 3×3, not 2×2 as was AB. In particular, matrix multiplication is *not* commutative. You cannot switch the order of the factors (that is, the matrices in the product) and expect to end up with the same result. For matrix multiplication, AB no longer equals BA.

WebMatrix multiplication basically means to follow a set of pre-defined rules when multiplying. ... Matrix multiplication is not commutative, which means their order is important. When multiplying matrices the right-most matrix is first multiplied with the vector so you should read the multiplications from right to left. WebThe matrix multiplication code does not care whether the matrices happen to be stored in column-major or row-major order. The same cannot be said for vector/matrix multiplication. And here's why. Vector/matrix multiplication is a falsehood; it cannot be done. However, you can multiply a matrix by another matrix.
