### Public Member Functions

**SymmSCMatrixSCExtrapError** (**StateIn** &)\
 **SymmSCMatrixSCExtrapError** (const **RefSymmSCMatrix** &)\
 void **save\_data\_state** (**StateOut** &)\
 Save the base classes (with save\_data\_state) and the members in the same order that the **StateIn** CTOR initializes them.  double **error** ()\

 Performs a scalar product between this and the given **SCExtrapError**.

### Additional Inherited Members

## Member Function Documentation

### double sc::SymmSCMatrixSCExtrapError::error ()` [virtual]`

Returns some measure of the total error.

Implements **sc::SCExtrapError**.

### void sc::SymmSCMatrixSCExtrapError::save\_data\_state (StateOut &)` [virtual]`

Save the base classes (with save\_data\_state) and the members in the same order that the **StateIn** CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from **sc::SCExtrapError**.

### double sc::SymmSCMatrixSCExtrapError::scalar\_product (const Ref\< SCExtrapError \> &)` [virtual]`

Performs a scalar product between this and the given **SCExtrapError**.

Implements **sc::SCExtrapError**.
