| class | boost::serialization::access |
A class that interpolates among stellar evolution tracks.
Uses a set of pre-computed evolution tracks to generate inrpolating functions that represents reasonably well the evolution of various properties of an arbitrary mass star as a function of age.
At present the only implementing class is MESA::Interpolator based on a set of MESA tracks.

Creates a fully functional stellar evolution interpolator.
| tabulated_masses | The stellar masses (in \(M_\odot\)) for which evolution tracks are tabulated. |
| tabulated_feh | The stellar [Fe/H] for which evolution tracks are tabulated. |
| tabulated_ages | A set of ages for each track in Gyr on the grid defined by track_masses and track_feh. The mass index varies faster. |
| tabulated_quantities | A set of stellar quantities for each age of each track. See StellarEvolution::QuantityID for the list, order and units of the quantities. |
| smoothing | How much to smooth each quantity when fitting. Use NaN for no smoothing. Corresponds entry by entry with tabulated_quantities. |
| nodes | How many nodes to use when smoothing each quantity (ignored if the corresponding smoothing entry is NaN - no smoothing). Corresponds entry by entry with tabulated_quantities and smoothing. |
| vs_log_age | Should interpolation be done vs. log(age) instead of age for each quantity? |
| log_quantity | Should interpolation be done of log(quantity) instead of quantity for each quantity? |
| num_threads | The number of simultaneosly running threads to use for the interpolation. |

| void StellarEvolution::Interpolator::delete_tracks | ( | ) |
Free all evolution tracks, rendering all created quantities unuseable!
Essentially an only explicitly called destructor. The reason for requiring explicit destruction is that generated quantities cannot be used after this method is invoked, and not invoking it simply causes a benign memory leak.

Loads data from serialization.
Only call this on objects NOT initialized using the default constructor (otherwise it has no data to save). Serializes state to file.
Recursively saves data of YRECEvolution and every class it depends on:
In _spline1dinterpolant_owner, serialize() serializes everything EXCEPT p_struct->x.data and p_struct->y.data, because those are just copies of the original data on which the spline was based and are not necessary for evaluating the spline.
| filename | The name of a file previously created using save_state() |

Return a single quantity interpolation to a given mass and [Fe/H].
The result must be destroyed when it becomes obsolete.
| quantity | The quantity for which to set-up the interpolation. |
| mass | The stellar mass to which to interpolate in \(M_\odot\). |
| feh | The stellar [Fe/H] to which to interpolate. |
