Steps:
1.Load the data using readmatrix function.
2.Here you have to find/relate the theta and rho value and use the polarplot function to plot the data.
3.In the 1st columns, the entire columns data are same.

4. Do you know how thease data values relate with polar form? If the B and C represents the cartesian coordinates, you may use cart2pol function to convert them to polar form (to find rho and theta)
