Details:


>> findobj('UserData',{1,2,3})
error: invalid conversion from cell array to logical value
error: called from
    findobj at line 252 column 15


One parenthesis is wrongly placed on this line.
wrong:

              elseif (isnumeric (pvalue{np} && isnumeric (p.(pname{np}))))

correct:

              elseif (isnumeric (pvalue{np}) && isnumeric (p.(pname{np})))


The function works with this correction for cell array property value.
However, it doesn't work anymore with empty numeric array property value.


>> findobj('UserData',[])
error: findobj: =: nonconformant arguments (op1 is 1x1, op2 is 0x0)
error: called from
    findobj at line 253 column 30


Lines 252 and 253 are superflue.
wrong:

              elseif (isnumeric (pvalue{np}) && isnumeric (p.(pname{np})))
                match(nh,np) = (pvalue{np} == p.(pname{np}));

correct:

              ##elseif (isnumeric (pvalue{np}) && isnumeric (p.(pname{np})))
              ##  match(nh,np) = (pvalue{np} == p.(pname{np}));


The function works with this correction for property values that are
empty/scalar/vector/matrix numeric arrays and cell arrays.
