{"library":"Scipy","prompt":"Problem:\n\n\nSuppose I have a integer matrix which represents who has emailed whom and how many times. I want to find people that have not emailed each other. For social network analysis I'd like to make a simple undirected graph. So I need to convert the matrix to binary matrix.\nMy question: is there a fast, convenient way to reduce the decimal matrix to a binary matrix.\nSuch that:\n26, 3, 0\n3, 195, 1\n0, 1, 17\nBecomes:\n0, 0, 1\n0, 0, 0\n1, 0, 0\n\nA:\n\n\n<code>\nimport scipy\nimport numpy as np\na = np.array([[26, 3, 0], [3, 195, 1], [0, 1, 17]])\n</code>\na = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
