There are many problems where for a matrix a  either the following

a fn"1 1 / a

or


a  f . g  |: a

generate a symmetric matrix.


I could well do with the saving of half the time on a computation.

1.    Has anyone good suggestions for handling this?
2. Isn't this such a common problem that some way of telling the interpreter to only do one triangle should be constructed?
