As there is no typing for the input argument of a macro automatic
overloading is difficult if it is not explicitely handled in the macro
code as in the example below:

function y=foo(x)
if typeof(x)<>'constant'  then
  execstr('y= %'+typeof(x)+'_foo(x)')
else
  y=x^2+1
endfunction

If the function to be overaloaded is stored in a library, there is an
other solution

Example: let define atanh for integer type
-->atanh(int32(2))
 !--error 10000
atanh: Mauvais type pour l'argument d'entrée n° 1: Matrice réelle ou
complexe attendu.

-->function y=atanh(x)
     elementary_functionlib.atanh //recall the default atanh
     if typeof(x)=="int32" then
         y=atanh(double(x))
    else  
         y=atanh(x)
    end
endfunction
-->atanh(int32(2))
