1. If your output variables all have equal number of rows, you indeed can use a 'table' datatype.
doc table
2. Otherwise, you could create a struct and define the output parameters as fields of that. This would require declaring single output variable at the function definition.
3. You could also store them in a cell-array and pass as the single output argument. However, this would require some indexing wrt the variables. So I might turn up saving the parameter names along.
function cellOutput = myFunc(inputArgs)
% Do something and collect outputs a, b, c
cellOutput{1,1} = 'a';
cellOutput{1,2} = a;
% and so on...
end
