Thank you for the answer. 2019-07-11 10:13:46 +0200 asked a question How to generate a nonsquare Vandermonde matrix? According to the documentation, we can generate a Vandermonde matrix using the method matrix.vandermonde() or vandermonde(). But they generate only square matrix. How do we generate a Vandermonde matrix which is not a square matrix? 2017-11-22 13:04:59 +0200 received badge ● Notable Question (source) 2016-04-28 10:18:01 +0200 received badge ● Popular Question (source) 2015-04-22 19:38:18 +0200 commented question How to generate an element from laplace distribution I found a way to do this by using numpy in sage. http://docs.scipy.org/doc/numpy/refer... import numpy numpy.random.laplace(loc,scal,size) will generate an element for laplace distribution. But it is not a very "sage" way to do it. And I am still concerned about my first question. 2015-04-22 00:02:16 +0200 received badge ● Student (source) 2015-04-21 21:58:52 +0200 received badge ● Editor (source) 2015-04-21 21:57:56 +0200 asked a question How to generate an element from laplace distribution Hi, I am wondering how to generate a random element according to laplace distribution. I tried the method RealDistribution(). But it failed. According to the reference manual, laplace distribution is not supported. http://www.sagemath.org/doc/reference... In the manual, there are some examples showing how to deal with uniform distribution, Gaussian distribution, etc. My questions are: (1) How do I know exactly which distributions are supported by the RealDistribution() method? (2) Is there anyway I can simply generate an element according to laplace distribution in sage? Thank you in advance.
