15.5.465 ptoc

ptoc( im [, nx, ny, x0, y0])

Transforms image im, which must be a two-dimensional float or double image, from polar to Cartesian coordinates, using bicubic interpolation. The first dimension of im is interpreted as the azimuth, spanning 360 degrees, and the second dimension as the radius, at a spacing of 1 px. If nx and ny are specified, then they indicate the dimensions of the returned image. If they are not specified, then two less than twice the size of the second dimension of im is used. If x0 and y0 are specified, then they indicate the Cartesian coordinates corresponding to the center of the polar transformation. If they are not specified, then one and a half less than the size of the second dimension of im is used.
