Web19 feb. 2024 · Sorry to add clarification the A (3x3) should multiply C(3x3) to form a new 3x3 matrix. That matrix (3x3) can then be multiplied by B (3x1) to produce a new 3x1. Hope this clarifys the issue that a 3x3 should be found to then find the 3x1. ... If B is really 1x3 and the order is supposed to be B*A*C(:,slice), then it is just. D = B*A*C; Then ...

Another way scalar multiplication relates to addition and subtraction is by thinking about \bold A-\bold B A −B as \bold A+ (-\bold B) A+(−B), which is in turn the same as \bold A+ (-1)\cdot\bold B A +(−1)⋅B. This is similar to how we can think about subtraction of two real numbers! mental illness in gymnastics
