## assigning result of timelimited function...

Maple

I want to assign the output of a function that has been passed to timelimit. Currently I have to pass, say, X in by reference (as a single element list) and do  timelimit( 0.5, F(X,args) ); where F := proc( X::list ); X[1] := f(args); end proc; --- which is not really desireable.

More generally I want my proceudre to skip loop iterations that are taking too long.

## Unexpected behaviour with chrem and vect...

Maple

I wrote some code involving chrem that broke in a recent version.

`> y := Vector([0]):`
`> yp := Vector([1]):`
`> trace(chrem);`
`> chrem( [y, yp], [1,3] );`
`{--> enter chrem, args = [Vector(1, [...], datatype = anything), Vector(1, [...], datatype = anything)], [1, 3]                                        n := 2                                    v, m := [0], 1                                        v := 0`

Has anyone been able to successfully install the Maple-Linbox package?

Basically when trying to make the maple configure linbox package one gets errors like:

error: no match for call to ‘(LinBox::BlasBlackbox<LinBox::Modular<double>

What would be the best way to compute the determinant of a very large (millions x millions) 0-1 matrix?
