{"library":"Numpy","prompt":"Problem:\nI want to convert a 1-dimensional array into a 2-dimensional array by specifying the number of columns in the 2D array. Something that would work like this:\n> import numpy as np\n> A = np.array([1,2,3,4,5,6])\n> B = vec2matrix(A,ncol=2)\n> B\narray([[1, 2],\n       [3, 4],\n       [5, 6]])\nDoes numpy have a function that works like my made-up function \"vec2matrix\"? (I understand that you can index a 1D array like a 2D array, but that isn't an option in the code I have - I need to make this conversion.)\nA:\n<code>\nimport numpy as np\nA = np.array([1,2,3,4,5,6])\nncol = 2\n</code>\nB = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
