Web3 Aug 2024 · I am trying to solve a series of the linear equations Ax=b. A is a large sparse positive definite matrix, in n*n. And b is a vector, in n*1. Among this equations, "A" matrix are the same, while the vector "b" are different. They both come from finite element method (e.g. same geometry and different loadings in structral machanics).

WebInstant vector selectors allow the selection of a set of time series and a single sample value for each at a given timestamp (instant): in the simplest form, only a metric name is specified. This results in an instant vector containing elements for all time series that have this metric name. my baby book app
