Function File: [RT,xp] = radon(I, theta)
Function File: [RT,xp] = radon(I)

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.
