condicionales en matrices

Her an alternative to Terry's solution - assuming ORIGIN=0

BTW, to make Terry's version fully ORIGIN-independent the two column operators in the last but one line must use ORIGIN instead of 0 😉

Or using the column operator and vectorization

We could also do without any loop and vectorize the whole matrix multiplication, but because of the first text column its a bit more complicated as we can't simply write

because Prime won't allow to multiply a string by a number. So we have to extract the numerical data only first
