How to use an interpolated function in an analytical function

Hello, A a new COMSOL user, I am currently trying to run a simulation which has to define functions from solar spectra data.

I managed to create a new function called "solar_spectrum" by interpolation of a data file (see attached file) Now, I would like to use this function in another function called "modified_spectrum".

But it doesn't seem to work. I can't even display the first function when calling "solar_spectrum(x)" in the this new function...

Can you please help ?

Thanks

Jeremy!

Hi Jeremy,

it works if you omit the units everywhere. I remember having teared my hair about such issues before. I prefer to manually scale everything to stay with basic SI units.
