Getting an Error while runnig pso algorithm

While running PSO algo and calling a styblinski-tang function get an error msg like

error in untitled3 (line 48)

[~, fBest, info] = PSO(objFun, x0, xLow, xUpp, options);

i take the PSO code and Styblinski-tang function code from matlab itself.

How i can remove this error.

There would have been more error message than just that.

When you say that you took the PSO code from matlab itself, do you mean that you took a copy of particleswarm.m and renamed it PSO.m ??

Or do you mean that you took PSO.m from the File Exchange contribution https://www.mathworks.com/matlabcentral/fileexchange/72388-pso-for-training-a-regular-autoencoder ?
