Function Documentation

cast_basis()

template<typename T >

std::vector< std::reference_wrapper< const T > > slymer::cast_basis

(

const BasisSet &

bset

)

Convert a generic basis set to basis functions with the specific type.

Exceptions

std::runtime_error

if a basis function in the basis set is not of the specified type.

Template Parameters

T	The intended type of each basis function.

Parameters

[in]

bset

The basis set.

Returns

A vector with cast references to the basis functions.

References T().

operator*() [1/2]

PolynomialCoeffs slymer::operator* ( const double  c, const PolynomialCoeffs &  poly  )

inline

Multiply a polynomial by a constant value.

Parameters

[in]	c	The constant value.
[in]	poly	The polynomial.

Returns

The product of c and the polynomial.

References c.

operator*() [2/2]

GaussianFunction slymer::operator* ( const double  lhs, const GaussianFunction &  rhs  )

inline

Multiply a GaussianFunction by a scalar.

Parameters

[in]	lhs	The scalar multiplicative factor.
[in]	rhs	The GaussianFunction.

Returns

The scaled GaussianFunction.

operator<<()

static std::ostream & slymer::operator<< ( std::ostream &  out, const BasisShell &  bs  )

static

References slymer::BasisShell::coeffs, slymer::BasisShell::exps, and slymer::BasisShell::type.

read_endian()

template<typename T >

static T slymer::read_endian ( std::istream &  in, const bool  swap  )

static

Read bytes from a binary file into the specified type.

Attempts to account for the endian-ness of the binary data. This should hopefully make the routine more robust to running NWChem jobs on one machine and processing the files on another.

Template Parameters

T	Type of data to be read (only really need the size).

Parameters

[in,out]	in	The input stream.
[in]	swap	Change the endian-ness of the read data?

Returns

The read data, in the requested type.
