spmatrix — SciPy v1.16.0 Manual (original) (raw)
This class provides a base class for all sparse matrix classes.
It cannot be instantiated. Most of the work is provided by subclasses.
| __mul__(other) | |
|---|---|
| asfptype() | Upcast matrix to a floating point format (if necessary) |
| getH() | Return the Hermitian transpose of this matrix. |
| get_shape() | Get the shape of the matrix |
| getcol(j) | Returns a copy of column j of the matrix, as an (m x 1) sparse matrix (column vector). |
| getformat() | Matrix storage format |
| getmaxprint() | Maximum number of elements to display when printed. |
| getnnz([axis]) | Number of stored values, including explicit zeros. |
| getrow(i) | Returns a copy of row i of the matrix, as a (1 x n) sparse matrix (row vector). |
| set_shape(shape) | Set the shape of the matrix in-place |
| todense([order, out]) | Return a dense representation of this sparse matrix. |
