Loop through ,mat files and find a specific column with conditions

If you have MAT files you load them using the load function. No need to use fopen or fread.

Fiber detection Hough Transform

Very small and fine features. You might try the 2D FFT and see if this provides a better way to estimate rotation.

How to rotate or mirror the contents in the figure with axes?

Can you re-plot with new y values, y = 500 - y? Basically reverse the order of the y values before plotting.

Your control points do not match up, and the last control point actually does not appear in the distorted image.
