A GaussianShell constructor. Users of GaussianShell must pass pointers to newed memory that is kept by GaussianShell and deleted by the destructor. The arguments for the following ctor are:

• ncn is the number of contracted functions (1 except for SP and gen. con.)
• nprm is the number of primitives
• e gives the exponents (length nprm)
• am gives the angular momentum (length ncn)
• pure is 1 for pure am and 0 for cartesian (length ncn)
• c are the contraction coefficients (length ncn by nprm)
• pt describes whether the primitive functions are to be considered normalized or unnormalized. This effects whether or not c is manipulated to give the correct normalization.
• If do_normalize_shell is true (the default), then the shell normalization constants will be folded into the coefficients.

A GaussianShell constructor. In this ctor pure is either GaussianShell::Cartesian or Gaussian::Pure and all of the contracted functions are treated in that way. (The user doesn\'t need to compute generate a int*pure vector in this case.)

Construct a GaussianShell from KeyVal input. If pure is nonzero Cartesian functions will be used, otherwise, solid harmonics will be used.

Returns a radius. All functions in the shell are below threshold outside this radius.

Returns a bound for the basis function. This bound is defined so that it is positive and monotonically decreasing as a function of r.

Print the object.

Reimplemented from sc::DescribedClass.

Returns the intra-generalized-contraction overlap matrix element <con func1|con func2> within an arbitrary constant for the shell. func1 and func2 are determined according to the axis exponents, a1, b1, c1, a2, b2, and c2.

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::SavableState.

Compute the values for this shell at position r. The basis_values argument must be vector of length nfunction().
