Matrix B has four nonzero rows, hence the row rank of B, as well as the row rank of A, is four. There are four 5-tuples in D, so it follows from Theorem 3 that S is linearly independent. We can extend Theorem 3 to all finite-dimensional vector spaces, not just n-tuples. We...

A row-vector norm comparison method includes: combining constituent elements of a matrix to generates a plurality of combination results of the constituent elements; multiplexing the combination results to calculate factors constituting an adjoint matrix of the matrix; squaring the calculated factors and ...
I have a tensor which is simply a vector, vector = [0.5 0.4] and tf.shape indicates that it has shape=(1,), I would like to replicate the vector m times and have the shape of [m, 2], so for m = 2, matrix = [[0.5 0.4], [0.5 0.4]]. How do I achieve that using tf.ti...
Asked 11 years, 3 months ago Modified 5 months ago Viewed 219k times 111 Is there a good way of differentiating between row and column vectors in numpy? If I was to give one a vector, say: from numpy import * v = array([1,2,3]) they wouldn't be able to say weather I ...
