I have error while running my M file.
My function handler is as follows
h=@(x) rmse_test(x,FcnArgs{net:inputs:target});
But i'm getting error like this
Undefined function or variable 'FcnArgs'.
Error in genetic_algorithm (line 25)
h = @(x) rmse_test(x,FcnArgs{net:inputs:targets});
createAnonymousFcn is inbuilt function like this
function fcn_handle = createAnonymousFcn(fcn,FcnArgs)
%CREATEFUNCTIONHANDLE create an anonymous function handle
%
% fcn: A function handle
% args: A cell array of extra arguments to user's objective/constraint
% function

% $Revision: 1.1.6.1 $Date: 2011/10/27 00:34:50 $
fcn_handle = @(x) fcn(x,FcnArgs{:});
Could anyone help me to solve this error..??

Your function handler should not be that. Your function handler should be the result of calling
createAnonymousFcn( @rmse_test, {net, inputs, target})

Now i changed my function handler like this
h = @(x) rmse_test(x,{net:inputs:targets});
after changing i'm getting error like this
Undefined function 'colon' for input arguments of type 'network'.
Error in @(x)rmse_test(x,{net:inputs:targets})
Error in createAnonymousFcn>@(x)fcn(x,FcnArgs{:}) (line 11) fcn_handle = @(x) fcn(x,FcnArgs{:});
Error in fcnvectorizer (line 14) y(i,:) = feval(fun,(pop(i,:)));
Error in makeState (line 47) Score = fcnvectorizer(state.Population(initScoreProvided+1:end,:),FitnessFcn,1,options.SerialUserFcn);
Error in gaunc (line 41) state = makeState(GenomeLength,FitnessFcn,Iterate,output.problemtype,options);
Error in ga (line 351) [x,fval,exitFlag,output,population,scores] = gaunc(FitnessFcn,nvars, ...
Error in genetic_algorithm (line 55) [x_ga_opt, err_ga] = ga(h, 3, ga_opts); Caused by: Failure in user-supplied fitness function evaluation. GA cannot continue.
how can i solve this error.could you please help me..??

When i change my function handler as mentioned above i'm getting error like this
Index exceeds matrix dimensions.
Error in setwb (line 32) net.IW{i,j}(:) = x(inputWeightInd{i,j});
Error in rmse_test (line 17) net = setwb(net, x');
