ergo_real | get_largest_simple_integral (const BasisInfoStruct &basisInfo) |
Computes the largest integral of any primitive in the basis set, when any x y z factors are ignored. | |
ergo_real | get_max_basis_func_abs_value (const BasisInfoStruct &basisInfo) |
Computes an estimate for the largest absolute value that any basis function takes. | |
int | get_basis_func_extent_list (const BasisInfoStruct &basisInfo, ergo_real *basisFuncExtentList, ergo_real maxAbsValue) |
Computes an "extent" for each basis function in the basis set. | |

int get_basis_func_extent_list | ( | const BasisInfoStruct & | basisInfo, | |
ergo_real * | basisFuncExtentList, | |||
ergo_real | maxAbsValue | |||
) |
Computes an "extent" for each basis function in the basis set.
The "extent" is such that the value of the function is smaller than maxAbsValue at distances beyond the "extent".
ergo_real get_largest_simple_integral | ( | const BasisInfoStruct & | basisInfo | ) |
Computes the largest integral of any primitive in the basis set, when any x y z factors are ignored.
This is useful for getting rough estimates of basis function extents.
ergo_real get_max_basis_func_abs_value | ( | const BasisInfoStruct & | basisInfo | ) |
Computes an estimate for the largest absolute value that any basis function takes.
Useful as "worst case" when you want to find out the largest contribution to the density that a basis function can be part of.
