Error while running ga code. How to use function handler .? Undefined function or variable 'FcnArgs'

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

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');
