Hello,

I am attempting to use the interp2 function with a for loop. The following code is what I have:

%% For loop for bsfc interpolation

for i = 1:1486

    XqWG =[EngineRpm(1:41)];
    YqWG(i,:) = [BrakeTorqueT(i)];
    VqWG = interp2(X,Y,V,XqWG,YqWG);
end

where EngineRpm is a 1X41 and BrakeTorqueT is 1486X41. Here I need to hold each value of EngineRpm(XqWG) constant so that, that single value is used to interpolate against all BrakeTorqueT values (YgWG).

The problem right now is the interpolation uses only the first column value from EngineRpm for every subsequent column in BrakeTorqueT (IE EngineRpm never moves from (1,1) to (1,2) when proceeding through the loop).I need each of the 41 columns to be interpolated with the 41 columns of BrakeTorqueT. In other words, what I need is for the EngineRpm (1,1) to be a constant XqWG value for all YqWG (1:1486,1) in the first column of Vq, then EngineRpm (1,2) is constant (XqWG) for all YqWG (1:1486,2) etc. as the loop proceeds to interpolate all the data. I hope my question has been clear, I apologize in advanced for any confusion my wording causes. Thank you.
