Such a definition could be done in form of an alpha string which is interpreted by the function that follows immediately ( in a FOCAL program).

I know that there are special functions for row- and column-sums, determinants, cross-products ... but that doesn't really help much. Real-world numerical algorithms ( like differential equation solvers, simplex method etc. ) always need individual combinations of matrix elements that cannot be reduced to standard functions like the above mentioned ones!

Very true Michael, but I'm afraid you overestimate my abilities. Such an implementation would no doubt require a variable management facility completely lacking in the platform, and writing it from the scratch is a very tall order.

Perhaps somebody else can get it started and we'll join in ;-)
