Angles for calculating radon tansform
Matrix of the Radon transform for one of the angles in theta.
Radial coordinates corresponding to each row of RT.
Calculates the 2D-Radon transform of the matrix I at angles given in THETA. To each element of THETA corresponds a column in RT. The variable XP represents the x-axis of the rotated coordinate. If THETA is not defined, then 0:179 is assumed.
