Related to this Question True or false. The n by n identity matrix is an elementary matrix. If A is a square matrix such that AA equals the zero matrix, then A must equal the zero matrix. True or false? If A is an invertible square matrix that is row equ...
We consider linear equations y = Φx where y is a given vector in ℝ<sup>n</sup> and Φ is a given n × m matrix with n < m ≤τn, and we wish to solve for x ∈ ℝ<sup>m</sup>. We suppose that the columns of Φ are normalized to the unit <sub>2</sub>-norm, ...
I did some search but found nothing related, is there any clue for this problem? Contributor rafaelvalle commented Dec 13, 2018 • edited That's probably not a problem with PyTorch. A matrix is singular if its determinant is zero, in which case it has no inverse. The loss function us...
