{"library":"Numpy","prompt":"Problem:\nIs there a way to change the order of the matrices in a numpy 3D array to a new and arbitrary order? For example, I have an array `a`:\narray([[[10, 20],\n        [30, 40]],\n       [[6,  7],\n        [8,  9]],\n\t[[10, 11],\n\t [12, 13]]])\nand I want to change it into, say\narray([[[6,  7],\n        [8,  9]],\n\t[[10, 20],\n        [30, 40]],\n\t[[10, 11],\n\t [12, 13]]])\nby applying the permutation\n0 -> 1\n1 -> 0\n2 -> 2\non the matrices. In the new array, I therefore want to move the first matrix of the original to the second, and the second to move to the first place and so on.\nIs there a numpy function to do it? \nThank you.\nA:\n<code>\nimport numpy as np\na = np.array([[[10, 20],\n        [30, 40]],\n       [[6,  7],\n        [8,  9]],\n\t[[10, 11],\n\t [12, 13]]])\npermutation = [1, 0, 2]\n</code>\nresult = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
