Simulation of GAPID code is yielding invalid "initializega" function (Type: double, MATLAB version:7.7)what is to be done?

%Initialising the genetic algorithm
populationSize=80;
variableBounds=[-100 100;-100 100;-100 100];
evalFN='PID_objfun_MSE';
%Change this to relevant object function
evalOps=[];
options=[1e-6 1];
initPop=initializega(populationSize,variableBounds,evalFN,...
evalOps,options);
%

after simulation i'm getting following error: ??? Undefined function or method 'initializega' for input arguments of type 'double'.

Error in ==> rky at 20 initPop=initializega(populationSize,variableBounds,evalFN,...__________________________________________________________________

Do you have the Global Optimization Toolbox installed?

[meghana]

No. can you please assist me in doing that please.

[meghana]

same problem is occurring after having global optimization toolbox

[Walter Roberson]

Does the ver() command show that toolbox now? Does

which -all initializega

show any results?

Which MATLAB version are you using?

[Aj_ti]

i'm facing the same problem. i have the toolbox. and my matlab version is r2012a. please help me

[lithika]

 This is the going through of ver() command in matlab. I have global optimisation toolbox also but the code for the GA doesnt work.
Suggest an answer.

[lithika]

all initializega shows ans=1;

How to solve this problem to make the code run????

[Khushboo Rani]

exactly ...it is showing initializega is undefined

[Walter Roberson]

initializega is part of the third-party Genetic Algorithm Optimization Toolbox, https://github.com/estsauver/GAOT
