I have a main function called mainfun
function [out1,out2]=mainfun(input)
[out1]=fun1(input);
[out2]=fun2(input);
end
so my question is ,may be i am calling my mainfun,and I want to display the individual result from different sub function,but how to display if there is any error in one subfunction ?
like an example ,
if in my fun1 there is eroor then also i want to get the fun2 result .

You can create a helper function
function varargout = safe(fcn, varargin)
try
[varargout{}] = fcn(varargin{:}) ;
catch ME:
varargout(:) = {nan};
end
With that you can
[out1] = safe(@fun1,input);
[out2] = safe(@fun2,input);

[F1,M1,deobj1a,bb1,deobj2a,Xa,Coap,Co1ap,combap,obj1ap,obj2ap,comb1ap,comb3ap,comb4ap,comb5ap,comb6ap,comb12ae,obj11ae,obj22ae,comb11ae,comb22ae,comb33ae,comb44ae,comb55ae,comb66ae,t1a,t2a,t4a,t3a,t5a]=safe(@Together2,C,Dij,i,j,Fj,Uij,DQij)
Output argument "varargout{2}" (and maybe others) not assigned during call to "safe".
First i made one extra function called safe ,as guided by you .then i am just calling my subfunction .but its showing this kind or output.

function varargout = safe(fcn, varargin)
try
[varargout{1:nargout}] = fcn(varargin{:}) ;
catch ME:
varargout(1:nargout) = {nan};
end

function [out1,out2]=mainfun(input)
out1=nan;out2=nan;
try [out1]=fun1(input);
end
try [out2]=fun2(input);
end

You should initialize any output variable that might otherwise not be assigned to because of errors.
