Re: [Help-gsl] Integrating over a grid

Hi,

A am assuming 'grid' means 2D data set i.e. f(x,y) = z. Are you integrating data or a function? If it's data then I would suggest you create a two dimensional trapezium rule function. If it's an equation this would work too, however, you could also use GSL monte-carlo integration functions. These functions also work for higher dimensions.

Cheers,

Dan

Hi

I'm not sure if this is the right place for this question. Is there anyway I can use the GSL to integrate over a grid? The only option I can find is the "gsl_spline_eval_integ()" function. However, this actually makes an interpolating object and then integrates. Are there any others?

Thanks!

Kind Regards
