WebJan 12, 2024 · This is a short visual description of computing a 2D affine transformation using a single matrix multiplication step, something that requires a bit of dimensional trickery. I’m trying to get ... One of the main motivations for using matrices to represent linear transformations is that transformations can then be easily composed and inverted. Composition is accomplished by matrix multiplication. Row and column vectors are operated upon by matrices, rows on the left and columns on the right. Since text reads from left to right, column vectors are preferred when transformation matrices are composed:
