MATLAB: Using a loop and counter for parametric equations

counterMATLABMATLAB and Simulink Student Suitenested for loopnewbieparametric study

I'm very new to MATLAB so I am aware this code is probably atrocious. Please speak clearly!
I have an equation for calculating wave power density (E) in an ocean wave. It has three variables (H, T, and h) with different numerical ranges. (i.e. H ranges from 1 to 3, T ranges from 5 to 22, and h ranges from 5 to 6.) I want to create a FOR loop where MATLAB will plug in different numbers, with increments of 1, essentially being a parametric study. I can't find any clear videos or links on nested for loops with counters.

Hi
Here is the solution of your task:
function E = realED(H, T, h)
%




%
%
rho=1030;
g=9.81;
%
%
L = zeros(numel(H), numel(T), numel(h));
k=L;
Cg=L;
E=L;
for ii=1:numel(H)
    for m=1:numel(T)
        for jj = 1:numel(h)
            L(ii, m, jj) = (g*T(m)^2)/(2*pi*tan(h(jj)))*((4*pi)^2)*h(jj)/(g*T(m)^2)^3;
            k(ii, m, jj)=2*pi/L(ii, m, jj);
            Cg(ii, m, jj) = .5*((1+((2*k(ii, m, jj)*h(jj))/sin(h(jj))))*2*k(ii,m,jj)*h(jj))*L(ii, m, jj)/T(m);
            E(ii, m, jj) = ((rho*g)/16)*(H(ii)^2)*Cg(ii, m, jj);
        end
    end
end
Good luck
