Hello Gurus,Pundits& Bosses of IDL,

Need help on 'int_tabulated'. One of the array has duplicate
elements(=same elements) and thus int_tabulated refuses to move any
further.

Is there any way out?

I tried QROMB, QSIMP etc. I can not use them because to do that I need
to define a 'function' which they integrate. I can not make a function
out of my 2 arrays (at least that's what I think).

However,the thing I like about them is that, you can specify step
size, which cant be done in int_tabulated.

Is there any procedure/function which can handle 1) repeatable
elements or same elements in array and also 2) can specify step size.

Any help will be greatly appreciated.

Thanks in advance.

Best,

TA
