I have a set of 4 parameters that I'm going to use to test an algorithm. I'm trying to created nested for loops to iterate through each possible combination (each parameter has 5 values to test).
But I also want to export this as a table, where later there will also be results from each combination (row).
This is what I have so far :
K = [0.9 0.99 0.999 0.9999 0.99999];
L = [1e-2 1e-4 1e-6 1e-8 1e-10];
maxAccelArr = [];
tauArr = [];
stayAliveArr = [];
PTerminateArr = [];
for i=1 : 5
maxAccel=9.8*i; %acceleration
maxAccelArr(i) = maxAccel;
for j= 100 :100: 500
tau=j; %maneuver time
tauArr(j/100) = tau;
for k = 1 : length(K)
PStayAlive= K(k); % stay alive
stayAliveArr(k) = PStayAlive;
for l = 1:length(L)
PTerminate=L(l); % termination probability
PTerminateArr(l) = PTerminate;
end
end
end
end
% save paremeter testing values as a table
parameterTest = table(maxAccelArr.', tauArr.', stayAliveArr.', PTerminateArr.');
filename = 'parameter_test.xlsx';
writetable(parameterTest, filename);
But this is generating a table with only 5 rows each, not all possible combinations. Any tips on how to accomplish this?

There is another thread about this topic. You should be able to find a solution there:
