inline function returning multiple output variables

tdata = table(["US";"US";"US";"UK";"UK";"TW";"TW";"TW";"TW"], [1;1;5;1.20000000000000;3;4;5;1;2],'VariableNames',{'name','Loss'});
tecdf = @(x) ecdf( x, 'Function', 'survivor');
tout = varfun( tecdf, tdata, 'GroupingVariables','name','Input','Loss')

tout = 11×3 table
    name    GroupCount    Fun_Loss
    ____    __________    ________

    "TW"        4               1 
    "TW"        4            0.75 
    "TW"        4             0.5 
    "TW"        4            0.25 
    "TW"        4               0 
    "UK"        2               1 
    "UK"        2             0.5 
    "UK"        2               0 
    "US"        3               1 
    "US"        3         0.33333 
    "US"        3               0 

tout only contains the first output from ecdf function. Is there a way to have it returns both output variables?

Thanks,

A wrapper is needed.

tdata = table(["US";"US";"US";"UK";"UK";"TW";"TW";"TW";"TW"], [1;1;5;1.20000000000000;3;4;5;1;2],'VariableNames',{'name','Loss'});
tecdf = @(x) ecdfWrapper( x, 'Function', 'survivor');

tout = varfun( tecdf, tdata, 'GroupingVariables','name','Input','Loss')

tout = 11×3 table
    name    GroupCount         Fun_Loss     
    ____    __________    __________________

    "TW"        4               1          1
    "TW"        4            0.75          1
    "TW"        4             0.5          2
    "TW"        4            0.25          4
    "TW"        4               0          5
    "UK"        2               1        1.2
    "UK"        2             0.5        1.2
    "UK"        2               0          3
    "US"        3               1          1
    "US"        3         0.33333          1
    "US"        3               0          5

function out=ecdfWrapper(x,varargin)

  [o1,o2]=ecdf( x, varargin{:});

  out=[o1,o2];
end

After which SPLITVARS might also be useful:

Rather than have to have an anonymous function use a wrapper function, why not just make the anonymous function into a regular function? Then there's no need for the anonymous function anymore.
