How does imwarp handle complex numbers?

I have a complex image I (an nxm array of complex numbers). I noticed that imwarp accepts complex images as input.

So this code:

J=imwarp(I, tform, 'linear');

will produce an output, that, on visual inspection seems to make sense.

But I could't find any information on how exactly the interpolation of the pixel values was done. Does anyone know about it or could point out documentation?

Thanks!

The interp option uses the same mechanism as it is in regular interp1, interp2, ....etc.

With a complex image in imwarp, interpolation operates individually on the real and imaginary parts separately.
