Hi!
I have created an hydraulic system on Simulink and I have a big set of data from the real system. What I am trying to do is to import this data into Simulink so that I can run there my simulation and see where the simulation data falls.
I tried to use a lookup table, but apparently I can just put one input data set, but in my case I have got several, as I recorded data for different pump rpms.
Does anyone know if there is a better tool than a lookup table for this purpose?
Thank you!!

2-D lookup table or n-D lookup table will do. Check the block document for examples.

But in the n-D lookup table to me it looks like I can just put n input data (breakpoints) and one output data (table data). Please tell me if I'm wrong.
Because I have this plot, so I have a different set of x and y data for each rpm measurement. I am attching the plot to clarify what I'm saying.
Do you think I should instead put as x source the input port instead of dialog?

A 2-D lookup table is sufficient for this case. Take a look at the example model and figure it out.
