Mata’s operators, such as + (addition) and * (multiplication), work as you would expect. In particular, * performs matrix multiplication: : A = (1, 2 \ 3, 4) : B = (5, 6 \ 7, 8) : A*B 1 2 +---+ 1 | 19 22 | 2 | 43 50 | +---+ The first element of the...

Ought it be possible for Stata's code to recognise when the result of a matrix multiplication is supposed to be a symmetric matrix? Whether or not this should be called a "bug", it may still be the case that it's not possible for our friends at Stata Corp to fix it. If so, then...
