[Zr, R] = radialavg(z,m,xo,yo) computes the average along the radius of a unit circle inscribed in the square matrix z. The average is computed in M bins. The radial average is not computed beyond the unit circle, in the corners of the matrix z. The radial average is returned in Zr and the mid-points of the M bins are returned in vector R. Not a Number (NaN) values are excluded from the calculation. If offset values xo,yo are used, the origin (0,0) of the unit circle about which the radialavg is computed is offset by xo and yo relative to the origin of the unit square of the input z matrix.
