MATLAB: Finding difference between two curves

averaging curvesimporting excel datasubtracting curves

I am very very new to matlab. I need to find the average of two curves and then subtract it from the third. The problem is that although they have the same limits they do not have the same x-values.

y1=rand(1,10);
y2=rand(1,12);
y3=rand(1,15);
out=y3-mean([y1 y2])

Look at this part of your code

for
    j=1:360
end

It's not correct, and even it's corrected

for j=1:360
end

This doesn't mean anything, maybe what you want is this:

syms x
Fun = (sqrt(7.447.*(200-x).*(2.0720.*x-200.*sqrt(9.01)+sqrt(9.01.*200^2- 7.9810*200.*x))))/8;
h=1;
zi = 1:360;
x=0:h:200;
Fun1 = matlabFunction(Fun);
for i=1:(length(x)-1)
    y1 = Fun1(x(i));
    z1 = Fun1(x(i));
    x2 = x(i)+h;
    y2 = Fun1(x(i+1));
    z2 = Fun1(x(i+1));
    x3 = x(i)+h;
    for   j=1:360
        y3 = y2*cos((pi/180)*zi(j));
        z3 = z2*sin((pi/180)*zi(j));
        T1 = [0, y3-y2, z3-z2];
        T2 = [x(i)-x(i+1), y1-y2, z1-z2];
        Vec = cross(T1,T2);
        deltal = sqrt((y2-y1)^2+h^2);
        deltazi = sqrt(z3^2+(y2-y3)^2);
        dA11 = deltal.*deltazi;
    end
end
