Optimization: I cant figure out why my while loop doesn't stop?

I have a for function inside of a for loop which is inside of a while loop. The loop should be stopping before it reaches the 10,000.

%% Declaration
a = 10;
b = 9.5;
r = 0;
i = 1;
s = 92101;
h = 0.5;
n = s + i + r;
yes = 0;
inc = 0;
numberBeds = 267.093;
%% Get numbers
while yes == 0
    % Get infected
    for k = 1:1:1000
    [ sN, iN, rN ] = DiseaseStep( s, i, r, n, a, b, h );
    sN(k) = sN;
    iN(k) = iN;
    rN(k) = rN;
    [m,~] = max(iN);
    m = m * 0.024;
    end
    % Stop loop if
    if m >= numberBeds
        yes = 0;
    else
        yes = 1;
    end
    % Increment
    inc = inc + 1;
    % end loop
    if inc == 10000
        yes = 1;
    else
        yes = 0;
    end
    % Increase beds
    numberBeds = numberBeds + 0.001;
    % Adjust budget
    budget = budget + (0.001 * 5000);
    % Decrease a
    a = a - 0.001;
end
function [ SOut, IOut, ROut ] = DiseaseStep( s, IIn, RIn, n, a, b, h )
%DiseaseStep This function is going to take in the values needed to
%calculate change over time and then change. Then, it is going to calculate
%the values of I,S,R after one step
n = s + IIn + RIn;

IOut= IIn+(h*(((a.*s.*IIn)./n)-(IIn/b))); %equation

SOut= s+(h*((-a.*s.*IIn)./n));

ROut= RIn+(h*(IIn/b));
end

In this part you set yes == 0 in every loop before inc reaches 10000. So even if your other condition sets it to yes == 1, it will not stop before inc == 10000 because you set yes == 0. A 'while' loop it always finishes one full loop before checking the condition, it does not check it midway.

    if inc == 10000
        yes = 1;
    else
        yes = 0;
    end

You could use the statement "break" if you want to break continuing the while loop.

    if m >= numberBeds
        yes = 0;
    else
        yes = 1;
        break
    end
