Hi there,

I have an interpolated 2d function defined using griddedInterpolant and I need to integrate over one of its arguments. I can't seem to find how to do it. I get the error:

Error using scatteredInterpolant/subsref
The input data has inconsistent size.

I can't make the inputs discrete and use trapz, I need the continous integral.

I have not used integral2 because I don't want to do a double integral. I want to fix one of the arguments and integrate over the other.

在 MATLAB Online 中打开

I got it. I have to give it the 'ArrayValued' option.

integral(@(w)VT0(50,w)0,100,'ArrayValued',1)

Thanks for the help anyways!
