My limited understanding of Matrix Multiplication is that by convension it's calculated from right to left; similar to how you would pipe functions together since function notation places the symbol to the left of the parenthesis f(g(h(x))
Generally speaking, when refering to the Nth matrix is it such that the 1rst matrix is the rightmost or leftmost matrix in the multiplication?
Thanks in advance!
Matrix multiplication can be performed both ways: left to right, and right to left. However, matrix multiplication is not conmutative, that is, $AB \neq BA$ (except for some very rare matrices). Since people read from left to right in the West, matrix multiplication is also red that way, so when refering to the $n$th matrix in the multiplication, we are implying the first matrix is the leftmost one.
