dear all i have an problem if any one can help me

when i used any example of particle swarm optimization , this example from help of particle swarm

fcn = @dejong5fcn;
       nvars = 2;
       lb = [-64 -64];
       ub = [64 64];
       [x,fval] = particleswarm(fcn,nvars,lb,ub)

it gives me this error i do not know why even though i have the particle swarm toolbox

Undefined function 'particleswarm' for input arguments of type 'function_handle'.

thank you

You also need to actually have the toolbox installed and as part of your license. The ver command should list your available toolboxes.

Thank you for answering Iam using MATALB 2015b full with optimization toolbox

particleswarm() is part of the Global Optimization Toolbox, not part of the Optimization Toolbox.

it gives me

>> which -all particleswarm
C:\Program Files\MATLAB\R2015b\toolbox\globaloptim\globaloptim\particleswarm.m  % Has no license available

but it was working before so why there is no license available

thank you very much for your helping

Were you using a Trial version? If so it might have expired.

Were you using a Student Version license obtained through a MOOC (Massive Open Online Course) ? If so then it might have expired.

Were you using a Student Version license under one of the Term options such as "9 months" or "1 year" ? If so then it might have expired.
