MathAction #274 Can't get a parameter in an anonymous function

Topics

There is still problem with handling closures, but this problem is fixed.

Theses functions are right :

Need to set:

fricas

)set function compile on

fricas

methodea a == select (t +-> t=3, expand (-10..2*a))

Type: Void

fricas

methodea 10

fricas

Compiling function methodea with type PositiveInteger -> List(
      Integer)

$\label{eq1}\left[ 3 \right]$

Type: List(Integer)

fricas

methodeb a == select (t +-> t=a, expand (-10..20))

Type: Void

fricas

methodeb 10

fricas

Compiling function methodeb with type PositiveInteger -> List(
      Integer)

$\label{eq2}\left[{10}\right]$

Type: List(Integer)

fricas

methode1 := a +-> select (t +-> t=3, expand (-10..2*a))

$\label{eq3}a \mapsto{select \left({{\left(t \mapsto{t = 3}\right)}, \:{expand \left({{\left(-{10}\right)}..{\left(2 \ a \right)}}\right)}}\right)}$

Type: AnonymousFunction?

fricas

methode1 10

$\label{eq4}\left[ 3 \right]$

Type: List(Integer)

This last function gives me a System error : The variable #:G30... is unbound. I think that the cause is the test a=t

fricas

methode2 :=  a +-> select (t +-> t=a, expand (-10..20))

$\label{eq5}a \mapsto{select \left({{\left(t \mapsto{t = a}\right)}, \:{expand \left({{\left(-{10}\right)}..{20}}\right)}}\right)}$

Type: AnonymousFunction?

fricas

methode2 10

$\label{eq6}\left[{10}\right]$

Type: List(Integer)
