在 MATLAB Online 中打开

x0 = min(speed) ; x1 = max(speed) ; nx = 100 ;
y0 = min(torque) ; y1 = max(torque) ; ny = 100 ;
x = linspace(x0,x1,nx) ;
y = linspace(y0,y1,ny) ;
[X,Y] = meshgrid(x,y) ;
Z = griddata(speed,torque,efficiency,X,Y) 
contour(X,Y,Z)

Where speed, torque and efficiency are vectors.

have you find the code to plot the efficiency map? i need it also if you can share

The answer has already been given. If you need something different, then it's up to you to describe what data you actually have and what specifically you want to do with it.

Hello dear, please guide me. I want to draw efficieny map, I have toque, speed data but no efficieny data. How can I get the efficieny data in Simulink model. Please gudie me.

Dear parveen kumar, I m facing difficulty to calculate the efficiency, so need your guidance,. May you give me your whatsapp no or email so that I may forward my simulink model to you. Please dear sir guide me

Sorry, at present wont be able to look at your model. If you want to plot the efficiency map, please check above example. You need speed, torque and efficiency data.
