The expression to the left of the equals sign is not a valid target for an assignment.

function[engtq_Nm,fuelrate_kgps]=calcengtq(xx,yy,zz,engpw_w,speed)

gearratio=[3.38,1.76,1.18,0.89,0.70,0.58];

engspeeds=speed./gearratio;

engtq_Nm=(engpw_w*30)./(pi.*engspeeds);

for i=1:1:6

fuelrategm/kwh(i)= interp2(xx,yy,zz,engspeeds(i),engtq_Nm(i));

end

fuelrate_kgps=fuelrategm/kwh.*engpw_w/36e8;

end

its giving me the error in line6. please help me with this

If I'm right, line 6 refers to this line of code:

fuelrategm/kwh(i)= interp2(xx,yy,zz,engspeeds(i),engtq_Nm(i));

You're trying to assign the result of interp2(xx,yy,zz,engspeeds(i),engtq_Nm(i)) to a variable called fuelrategm/kwh. Matlab doesn't see this as a single variable, but interprets it as fuelrategm divided by kwh. To the left of the equal sign, you should just have a single variable.

Try renaming it to fuelrategm_kwh, and you should be fine.
