I have a matrix with 480 rows and 640 columns. The matrix just contains numbers. How do I perform partial differentiation with respect to x and partial differentiation with respect to y on this matrix?
I am using Matlab 2015b.
Any help would be greatly appreciated

I would use the gradient function. It will do what you want. It assumes a constant ‘step’ in each direction, and you can specify that step for each direction.

Type
doc gradient
at matlab command prompt to see the documentation and see that it returns both partial differentials at once.
