WebAug 30, 2024 · For my application, the rows will have anywhere between 1 and 9 unique and nonzero entries. I've decided to utilize "sprand" for an example - I'm fairly new to using sparse matrices and am not the best programmer so forgive my naivety - and I've tried to choose a density within the aforementioned range. WebAug 7, 2016 · At a single point, off-diagonal elements of the metric tensor simply say that your coordinate system is not orthogonal. For example, if you use x ^ and x ^ + y ^ as your basis in the plane, the resulting metric has a cross term. Since the metric tensor is symmetric, you can always diagonalize it at a single point, so that's not very interesting.
