My quiver plot is coming out to be misaligned. Its rotated or flipped or something like that. how do i make it right?
Please help me with this problem of mine. I use R2015a version of MATLAB.

That looks like Amery Ice Shelf appearing as tiny red arrows in the middle of the eastern Ross Sea. Comparing its shape to the true Amery ice shelf, it looks like the quiver grid has been rotated and mirrored. Tinker with combinations of rot90 and fliplr until the quiver grid is correctly positioned.

Sir, is there a way to select any specific region's boundary, to analyze the data of just the points within?
I've downloaded the boundary files of Amery Ice Shelf, but its matrix size does not match that of mine, hence making it not overlap each other. What can be done about it?

It's hard to know exactly what you're trying to do. For any x,y points in your dataset you can use inpolygon to determine which points are within the boundaries of Amery Ice Shelf.
There's an example of how to do it for Wilkins Ice Shelf in the antbounds_data documentation here.
