RF = rotatef(F,THETA) rotates the vector/scalar field(s) F about an
angle THETA in the trigonometric direction (THETA is given in radians).
Points which have antecedent from outside the original field are
filled with 0.
RF = rotatef(V,THETA,'trunc') keeps only the central rectangular
area (with the aspect ratio kept constant) containing only valid (ie
nonzero) elements.
If no output argument, the result is displayed by showvec or showscal.
rotatef is useful for correcting vector/scalar fields obtained from
skewed images (e.g. misaligned camera).
Example: showvec(rotatef(loadset,0.1));
