x= a+b+c
where a=[ 1 2 3 4], b=[5 6 7 8] and c =[9 10 11 12 ]
How to use for loop for this.

What do you want to loop on, what is the output you are looking for?

If you want ‘x’ to be the sum of the columns of the three vectors, try this:
a = [1 2 3 4];
b = [5 6 7 8];
c = [9 10 11 12];
for k = 1:size(a,2)
x(k) = a(k) + b(k) + c(k);
end
A loop is of course entirely unnecessary here. You can just do this instead to get the same result:
x = a + b + c

I have to determine fuel_consumption at 60,80 ,120 and maximum speed. Fuel consumption is function of sfc,powerclutch and speed which is varying and the rest are constant.How to use for loop in this condition istead of writing 4 times mtf.png

I would do something like this:
sfcv = [600, 450, 330, 360]; % ‘sfc’ Vector
vel = [60, 80, 120, 420]; % ‘420’ Represents Maximum Speed, Since It Is Otherwise Undefined
for k = 1:numel(sfcv)
fuel_consumption(k) = sfc(k)*PowerClutch(k)*0.1/(1000*Rhofuel*vel(k));
end
figure
plot(vel, fuel_comsumption)
grid
xlabel('Velocity (km/h)')
ylabel('Fuel Consumption (L)')
Experiment to get the result you want.
