Try this:

numRuns = 10000; % How many times you want to run the simulation
allResults = zeros(numRuns, 3); % Array to hold all the results of all runs.
for k = 1 : numRuns
    % Run your simulation and get results.
    [w1, w2, w3] = MySimultationFunction(); 
    % Tack on the results for this run to our master results list of all runs.
    allResults(k, :) = [w1, w2, w3];
end

%Energy wavelets

%first number is phase number @ second number is level of decomposition

%Ea energy wavelet approximate

%Ed energy wavelet detailed

%level 1

[Ea11,Ed11] = wenergy(cA1,LA1);

[Ea21,Ed21] = wenergy(cB1,LB1);

[Ea31,Ed31] = wenergy(cC1,LC1);

[Ea1,Ed1] = wenergy(cG1,LG1);

%level 2

[Ea12,Ed12] = wenergy(cA2,LA2);

[Ea22,Ed22] = wenergy(cB2,LB2);

[Ea32,Ed32] = wenergy(cC2,LC2);

%level 3

[Ea13,Ed13] = wenergy(cA3,LA3);

[Ea23,Ed23] = wenergy(cB3,LB3);

[Ea33,Ed33] = wenergy(cC3,LC3);

w1=sum(Ed11(1,:))+sum(Ed21(1,:))+sum(Ed31(1,:));

w2=sum(Ed12(1,:))+sum(Ed22(1,:))+sum(Ed32(1,:));

w3=sum(Ed13(1,:))+sum(Ed23(1,:))+sum(Ed33(1,:));

s=[w1 w2 w3]

Image Analyst thanks for your concern

this is the last part of the code

numRuns = 10000; % How many times you want to run the simulation

allResults = zeros(numRuns, 3); % Array to hold all the results of all runs.

for k = 1 : numRuns

% Run your simulation and get results.

[w1, w2, w3] = MySimultationFunction(); % i made it [w1,w2,w3] = s(); and it gave me an error

Insufficient number of outputs from right hand side of equal sign to satisfy

assignment.

what i should i do?

% Tack on the results for this run to our master results list of all runs.

allResults(k, :) = [w1, w2, w3];

end

I think you need the function

function [w1, w2, w3] = MySimulationFunction()

[Ea1,Ed1] = wenergy(cG1,LG1);

[Ea12,Ed12] = wenergy(cA2,LA2);

[Ea13,Ed13] = wenergy(cA3,LA3);
[Ea23,Ed23] = wenergy(cB3,LB3);
