matrix indexing using parentheses Let me tell you a story. Once upon a time, perhaps even 10 minutes ago, when writing a new function (Bidiagonal) and testing it with strings, I replaced a direct function call argument with a predefined vector but forgot to remove the original function's argument. After a few seconds of gazing at the (correct) output from Bidiagonal, I realised that the notation V(3) for vector V should have raised an error, but it didn't.
After a bit of playing with a new, blank worksheet, I confirmed that to get an array's elements, one can use the standard subscripted index notation Mi,j or the standard programming language parenthesis notation M(i,j). And Little Red Riding Hood and Peter campaigned for a better public understanding of wolves, their role in ecology, and their treatment.
I have a vague, dusty, indistinct memory of coming across this notation before, perhaps even on this forum, but I'm not sure - it might be a case of déjà vu.
