- Matrices with independent normal entries. The default distribution of entries in matrices generated by random_matrix seems to be uniform over [-1,1]. Can that be changed?
- Random (normal) vectors with fixed sparsity, in the sense that only a given number of the entries are non-zero.
Thanks for any assistance.staffordTue, 28 Aug 2012 22:29:21 +0200https://ask.sagemath.org/question/9274/
