Rotate surf input matrices

[X,Y,Z] = ROTATESURF(x,y,z,euleraxis,eulerangle) rotates the SURF input data xyz, where x,y and z are matrices of the same size, according to the rotation axis euleraxis (vector) and the angle eulerange (radians).

SURF(X,Y,Z) displays the rotated object.

Omitting output arguments causes the object to be displayed with a SURF command and no outputs to be returned.

ROTATESURF(AX,...) plots into AX instead of GCA.

EXAMPLE:
eaxis = [1,1,1];
eangle = pi/4;
[x,y,z] = peaks(25);
[X,Y,Z] = rotatesurf(X,Y,Z,eaxis,eangle);
surf(X,Y,Z)
