## Virtual Class "ddenseMatrix" of Numeric Dense Matrices

### Description

This is the virtual class of all dense numeric (i.e.,
**d**ouble, hence *“ddense”*) S4 matrices.

Its most important subclass is the `dgeMatrix`

class.

### Extends

Class `"dMatrix"`

directly;
class `"Matrix"`

, by the above.

### Slots

the same slots at its subclass `dgeMatrix`

, see
there.

### Methods

Most methods are implemented via `as(*, "dgeMatrix")`

and are
mainly used as “fallbacks” when the subclass doesn't need its
own specialized method.

Use ```
showMethods(class = "ddenseMatrix", where =
"package:Matrix")
```

for an overview.

### See Also

The virtual classes `Matrix`

,
`dMatrix`

, and `dsparseMatrix`
