Entering simulink 3D look-up table data from MATLAB

  1. Apr 2, 2014 #1
    I have created a contour plot in MATLAB using the following code:

    >> NP=40;
    >> [RP TP]=meshgrid(linspace(min(RPM),max(RPM),NP),linspace(min(BMEP),max(BMEP),NP));
    >> BSFC_IT=griddata(RPM,BMEP,BSFC,RP,TP);
    >> NC=12;
    >> Fig1=figure;
    >> [CT HT]=contourf(RP,TP,BSFC_IT,round(logspace(log10(210),log10(400),NC)));
    >> colorbar;
    >> %clabel(CT,HT);
    >> xlabel('Engine Speed (rpm)')
    >> ylabel('BMEP (bar)')
    >> title('Contours of BSFC (g/kWh)')

    I would like to put all of my data in a 3D look-up table in Simulink, then when I insert a value for x and y it returns me a value for z.

    Is there any way I can do this? I've been looking at how to use 3D look-up tables but I can't get my head around it.

    Any help is much apreciated.
