Hi everybody,I'm doing some static structural analysis with Ansys Mechanical through Workbench 18.1 and I'm getting an error which is not helpful at all:An error has occurred in the Sparse Matrix Solver while processing the matrix values. Error code = 18
The way the sparse BLAS domain in oneMKL works is that the sparse matrix you are creating with the `mkl_sparse_d_create_csr` API from oneMKL does not own or copy over the arrays that you are passing into it, and it is users' responsibility to maintain the lifetime ...
In order to minimize memory requirements,the initial matrix A is usually overwritten by the coefficients of U and L, it being understood that the unit diagonal of L need not be stored. The elimination algorithm can be rearranged in several different ways. In particular, rewriting eqn (1) in...

The reverse Cuthill-McKee ordering is intended to reduce the profile or bandwidth of the matrix. It is not guaranteed to find the smallest possible bandwidth, but it usually does. Thesymrcmfunction actually operates on the nonzero structure of the symmetric matrixA + A', but the result is al...

Compute the error covariance matrix \(\Sigma _{\varepsilon }\) of \(M^{(j)}\). 3. For each lagged regressor block \(x \in {\mathbb {X}}\) not already present in the RHS of \(M^{(j)}\): (a) Let \(M^{+}_{j}\) denote the augmented block of equations obtained ...
Using sparse matrices to store data that contains a large number of zero-valued elements can both save a significant amount of memory and speed up the processing of that data.sparseis an attribute that you can assign to any two-dimensional MATLAB®matrix that is composed ofdoubleorlogicaleleme...
Following a recent update to the Matrix package, several users have reported errors related to functions that use methods from the Matrix package. These will typically result in error messages like: 'as_cholmod_sparse' not provided by pa...
