Hi,

When I try to use the example in "help patternsearch", I got this error:

 X = patternsearch(@(x) 3*sin(x(1))+exp(x(2)),[1;1],[],[],[],[],[0 0])
??? Error using ==> mean
Too many input arguments.

Error in ==> getinitial at 26 meanX = mean([Iterate.x],2);

Error in ==> pfminbnd at 13 [optimState,nextIterate,MeshSize,EXITFLAG,run] = ...

Error in ==> patternsearch at 353 [X,FVAL,EXITFLAG,OUTPUT] = pfminbnd(FUN,objFcnArg,initialX,numberOfVariables,Iterate, ...

Does anyone see this error before? Thank you very much.

Try to debug your program with the command:

dbstop if error

It looks to me, that you have overwrote some matlab function.
