Fzero using for loop

I have an anonymous function, im trying to find each fzero value as variable x in the anonymous function (AC) goes from 0:1:10, how can I do that?

Eq1 = @(A) 2A + A^2 - 5A
Eq2 = @(A) 3A + A^3 - 2A
B=5;
AC = @(A) B - 2 * integral(Eq1,5,A) - x * integral(Eq2,5,A);
j=1;
for x=0:1:10
        Z(j)=fzero(AC(x),0)
        j=j+1
end

You need to parameterize the function:

Note that it is usually simpler and more robust to loop over indices rather than looping over data, e.g.:

Eq1 = @(A) 2*A + A.^2 - 5*A;
Eq2 = @(A) 3*A + A.^3 - 2*A;
B = 5;
AC = @(A,x) B - 2*integral(Eq1,5,A) - x*integral(Eq2,5,A);
X = 0:1:10;
N = numel(X);
Z = nan(0,N);
for k = 1:N
    Z(k) = fzero(@(A)AC(A,X(k)),0);
end

Giving:

>> Z
Z =
       5.2309        5.033       5.0178       5.0122       5.0092       5.0074       5.0062       5.0054       5.0047       5.0042       5.0038

Passing extra parameters

AC = @(A,x) B - 2 * integral(Eq1,5,A) - x * integral(Eq2,5,A);
%%
Z(j) = fzero(@(A)AC(A,x),0)
