Interpolation Graph with Simulink (look-up table?)
显示 更早的评论
Hi,
I need to make e block with interpolation graph inside like this:
I've tried with 2D lookup table with Vgs-Vth values as columns, Drain to Source voltage as rows and Drain Current as Table, but it wants that columns be equal to rows (like a square matrix) while i've few values of columns respect to rows.

Is it possible to only use the rows whose column values you have and let the Lookup Table block interpolate for you? If that does not provide satisfactory results, you could consider using the Curve Fitting Tool (or similar analysis techniques) to figure out the data samples that you don't have.
