NDVI function in Python

[Elvis_de_JesúsDurán_Sierra]

Hi everyone!
I want to know if it is possible to call the NDVI function that is inside the Image analysis window of Arcmap 10.1 from a python script.
I have the following questions:
1. If it is possible, how can I call that function inside a python script???
2. Is it possible to access the source code of that function???

Regards.

Elvis,

I am not sure about the abilities for importing the function in python, however there was this post in technical blog that may be of assistance.

Hope this help!

Best,

Or you could look into functions like RasterToNumPyArray(arcpy).
