Rotate an array by 90 degrees in the counter-clockwise direction. The first two dimensions are rotated if the array has more than 2 dimensions.

Parameters

• a – (array_like) Array for rotate.

• k – (int) Number of times the array is rotated by 90 degrees

Returns

(array_like) Rotated array.

Examples:

>>> m = array([[1,2],[3,4]])
>>> m
>>> array([[1, 2]
      [3, 4]])
>>> rot90(m)
array([[2, 4]
      [1, 3]])
>>> rot90(m, 2)
array([[4, 3]
      [2, 1]])
