# scipy.sparse.dok

Dictionary Of Keys based matrix

Functions

`getdtype`(dtype[, a, default]) | Function used to simplify argument processing.
`isdense`(x) |
`isintlike`(x) | Is x appropriate as an index into a sparse matrix? Returns True
`isscalarlike`(x) | Is x either a scalar, an array scalar, or a 0-dim array?
`isshape`(x) | Is x a valid 2-tuple of dimensions?
`isspmatrix`(x) |
`isspmatrix_dok`(x) |
`upcast`(*args) | Returns the nearest supported sparse dtype for the combination of one or more types.

Classes

`dok_matrix`(arg1[, shape, dtype, copy]) | Dictionary Of Keys based sparse matrix.
`izip` | izip(iter1 [,iter2 [...]]) –> izip object
`spmatrix`([maxprint]) | This class provides a base class for all sparse matrices.
