Web5. For the base R matrix class we have the rowsum function, which is very fast for computing column sums across groups of rows. Is there an equivalent function or approach implemented in the Matrix-package? I'm particularly interested in a fast alternative to rowsum for large dgCMatrix-objects (i.e. millions of rows, but roughly 95% sparse). Webcupyx.scipy.sparse.linalg.spsolve(A, b) [source] #. Solves a sparse linear system A x = b. Parameters. A ( cupyx.scipy.sparse.spmatrix) – Sparse matrix with dimension (M, M). b ( cupy.ndarray) – Dense vector or matrix with dimension (M) or (M, 1). Returns. Solution to the system A x = b. Return type. c 语言 switch
