Hello,
I'm having some trouble with my octave coding and would appreciate any input on where the issue lies.
The coding is as follows:
<Moderator's note: code tags added. Please use them when posting code.>The issue I'm having lies in the population matrix computation; the cumtrapz integration is not recognizing the step process and all outputs from t = 2:101 in the population matrix are zeros. I would again appreciate any help to understand where the issue lies.
Thank You,
Jacob M.
I'm having some trouble with my octave coding and would appreciate any input on where the issue lies.
The coding is as follows:
Matlab:
age = [0:1:100]; %this is the age matrix, represented by a
time = [0:1:100]; %this is the time matrix, represented by tpopulation = zeros(101,101);
for a = 1:101;
population(a,1) = 0.5; %this is the initial population
B(a) = (1./(2.*a)); %this is the birthing probability at age (a)
endfor
for t = 1:100
for a = 2:101
population(1,t+1) = cumtrapz(B(a)); %this is the birth rate
population(a,t+1) = population(a-1,t); %this is the interation process
endfor
endfor
surf(age,time,population)
Thank You,
Jacob M.
