Hello all,
Here is a snippet of code:
MyArcTan := Function[{x, y},
Module[{result},
If[x == 0 && y == 0,
result = 0,
result = ArcTan[x, y]
];
result
]
];
In[725]:= Thread[MyArcTan[{-1, 0, 1}, 0]]
Out[725]= result$58407737
Somehow, when I thread my custom function MyArcTan[], it does not
execute the If[] test hence do not define the result...
How can I solve that ?
TIA
