I can compute the algorithm for these 3 arrays, but then I'm stuck on how to implement it. Do I need instead to write 3 functors that behave as arrays and use them with map function to map them into a sparse matrix? Do I need instead to write the whole sparse matrix as a functor?
我有一个相当大的稀疏矩阵A作为scipy.sparse.csr_matrix。它具有以下属性: A.shape: (77169, 77169)A.nnz: 284811011A.dtype: dtype('float16') Run Code Online (Sandbox Code Playgroud) 现在我必须使用将其转换为密集数组.toarray()。我对内存使用量的估计是 ...
sparse_matrix_t A; sparse_status_t ok=mkl_sparse_z_create_csr (&A,SPARSE_INDEX_BASE_ONE,nRows,nCols,ia,ia+1,ja,z); The handle A is generated for the complex array z and the integer arrays ia and ja. I am trying to understand if the data in the arrays is...
Hi@LukasMoll, you code example does not make sense to me. In order to create a random sparse matrix, you need to supply your random dense data to a cupyx matrix object, which manages a specific sparse format, for example CSR. Populating CSR matrix with random data could followthis exampl...
