Error using compose (line 86) First argument must be a string array, character vector, or cell array of character vectors. Error in composeFcn (line 4) h = compose(varargin{i},h); Error in Test1 (line 4) h = composeFcn(f1,f2,f3);

2   Fail
f = repmat({@(x)x+1},1,100); h = composeFcn(f{:}); assert(isequal(h(0),100));

Error using compose (line 86) First argument must be a string array, character vector, or cell array of character vectors. Error in composeFcn (line 4) h = compose(varargin{i},h); Error in Test2 (line 2) h = composeFcn(f{:});
