I thought the proper way to correct questionable results is to conduct and publish a follow-up study that independently looks at the same question with better data and better methodology. And wait until multiple independent teams have done

The problem with MATLAB is that idiomatic MATLAB style (every operation returns a fresh matrix) can easily become very inefficient: it leads to countless heap memory allocations of new matrices, resulting in low data-access locality, i.e. y

What exactly does he technically want to preserve? Does he really care about amplitude modulation? Or does he care about the frequency band (medium wave, HF) and its propagation properties? Or does he care bout the geographic reach of these
