Functions defined by integrales in IDL [message #5366] Mon, 04 December 1995 00:00

I have the following problem to solve with IDL:

f(a) is a function defined by an integral:
f(a)=integrate[g(a,x)dx] where the integration is made over a finite range.

I would like to get a numerical evaluation of f, knowing a.

The problem is that I can't pass "a" to any of the standard IDL integration
procedures (they all require the name of a function with only *one* parameter:
here x). The 2 D algorithms don't work either, since I am doing only one
integration.

So is there a standard solution to solve this problem or do I have to write
an integration routine accepting two inputs ?

Thanks in advance,

Miska Le Louarn
