The two dimensional rotation matrix which rotates points in the $xy$ plane anti-clockwise through an angle $\theta$ about the origin is.. Rotate an array by 90 degrees in the plane specified by axes. Rotation direction is from the first towards the second axis. Parameters. marray_like. Array of two ...
The function rotates each page of the array independently. Since a full 360 degree rotation ( k = 4 ) leaves the array unchanged, rot90(A,3) is equivalent to ...
