Hi
I would like to creat transformation matrix from each control point in position (x,y,z) and their distortion (dx,dy,dz) (11253x6 table) for image registration with CT image (512X512X309 uint16)
have any function or any idea for create geometric trasformation from data in excel table
thank you

You wouldn't use a transformation matrix to execute a deformation like that. You would just use griddedInterpolant or interp3 to re-interpolate image at query points (x+dx,y+dy,z+dz).
