I am not sure if Python is much faster than the MATLAB.
Have you tried bias_correction function provided in the ambhas Python library (

Programming / Re: R vs Python
« on: December 23, 2016, 05:05:24 PM »
According to you which is good for both statistical and Non-statistical analysis?Better based on ur experience can u suggest for what type of problems we should use MATLAB , R & Python Respectively ? Or by learning which language we can solve majority of problems ??

R and MATLAB are relatively better than Python for advanced statistical analysis. However for most commonly used stat is available in all.
If you learn any one of these, learning others is very easy. So just start with anyone. R and Python are better than MATLAB for handling GIS data. Python is relatively better for handling strings.

Which is easier to Learn, since learning and becoming critically good, like knowing nook and corner in any one of the programming languages  is itself difficult and challenging on ??
MATLAB has few datatype, so relatively easy to learn.

Is there any you-tube channel or website where they teach these algorithms from the scratch ?
Search in google and select the video option. You will find lots of videos. I prefer to learn from books. For MATLAB, I prefer: Basics of MATLAB and Beyond by Andrew Knight. For python, you can use Python in hydrology and other books are also mentioned in the forum. Just visit the Python section. For R, we added some notes - you can find in the R section of the forum.

Among MATLAB R and Python which has many GIS functionalities ???
Answered above.

For Beginners what one has to do, to become extremely good in a specific programming language because the net is flooded with so many teaching modules that we can't check each one and come to a conclusion .If we do so, we shall be left with learning less things with more time invested .
To learn programming, you need to program a lot. No other shortcut. Whatever assignment/problem you get, try to solve only in that programming language.

My advice, focus on the learning.

When you pose a question, please put it in a separate post.
