I'm working in xcos, and have two output data at some point. I have to process these, and give out a third output, which would be input as a third parameter to another part of the flow diagram.

I thought of using the scifunc block in the user defined functions in the xcos palette. The first two output data, are however, in the form of a structure, the same form that the 'From Workspace' block takes. The scifunc block doesn't seem to be accepting this as input data. It's giving an error: "Simulation problem".

Is there any way I could work around this, or try something else?

I want to do 2-D interpolation using the variables, with data from an excel sheet; so it's not possible in the xcos diagram itself.

Thanks
