Is there a method that I can call to create a random orthonormal matrix in python? Possibly using numpy? Or is there a way to create a orthonormal matrix using multiple numpy methods? Thanks. 解决方案 This is the rvs method pulled from the https://github.com/scipy/scipy/pull/5622/files,...

I am trying to create a huge boolean matrix which is randomly filled with True and False with a given probability p .起初我使用这段代码: N = 30000 p = 0.1 np.random.choice(a=[False, True], size=(N, N), p=[p, 1-p]) 但遗憾的是,它似乎并没有因为这个大的 N 而终止。所以我试...
