The issymmetric function from linalg expects a NumPy array, not a sparse matrix. The condition might not work as intended with a sparse matrix. You can convert the sparse matrix to a dense one using arr.toarray() and then use issymmetric or implement a custom approach to check symmetry on the sparse matrix.

To improve the error message, you could include the object type in the description:

Overall, the patch looks good. A few suggestions and comments will be provided below.

Consider setting a random seed for reproducibility before generating the sparse random matrix.

Replace the current assert message with a more informative one:
| assert sparse_mat.data.nbytes // 1024**2 > 4, f"Matrix size is not over gRPC message limit (4 MB): {sparse_mat.data.nbytes // 1024**2} MB" |

Nice addition of tests for symmetric dense and sparse matrices. It helps check if the server version meets the requirements.
Please make the suggested changes to the assert messages for better readability and submit the patch for review again.

Symmetric matrices are stored with upper triangular ones within MAPDL. storage_matrix = [[x x x x],
[. x x x],
[. . x x],
[. . . x]]
symmetric_matrix = storage_matrix + storage_matrix.T - diag(storage_matrix) |
Closes #195.
