Can I do pre-processing of S1A IW GRD product in MATLab

I want to do following pre-processing work on a S1-GRD product:
2.Apply Orbit file
4.speckle filtering
5. terrain flattening
6.terrain correction
and then “write” for further analysis of the end product.
Is it possible ? In GPT the snappy will automatically download the required files in steps 2,5 and 6 . in the case of MATLab how is it possible ?

Have you find the way to do processing in MATLAB
