I defined a user function by -
def dot(x,y):
return(sympy.Function('dot')(*(x,y)))
I want the _print_Function in str.py to handle this in a special way so
I modified it to
def _print_Function(self, expr):
if expr.func.__name__ == 'dot':
return '(%s|%s)' % (expr.args[0],expr.args[1])
else:
return expr.func.__name__ +
"(%s)"%self.stringify(expr.args, ", ")
but for example if "dot(a1,a2)" is in an expression then "dot(a1,a2)"
prints and not "(a1|a2)".
What am I doing wrong?
