Examples
math.rotate([11, 12], math.pi / 2) // returns matrix([-12, 11])
math.rotate(matrix([11, 12]), math.pi / 2) // returns matrix([-12, 11])
math.rotate([1, 0, 0], unit('90deg'), [0, 0, 1]) // returns matrix([0, 1, 0])
math.rotate(matrix([1, 0, 0]), unit('90deg'), [0, 0, 1]) // returns matrix([0, 1, 0])
math.rotate([1, 0], math.complex(1 + i)) // returns matrix([cos(1 + i) - sin(1 + i), sin(1 + i) + cos(1 + i)])
