`#include <shellrot.h>`

List of all members.

## Public Methods

void | init (int a, SymmetryOperation &, const Ref< Integral > &)
| Initialize the ShellRotation for Cartesian functions, given the angular momentum, a symmetry operation, and an Integral object.
void | init_pure (int a, SymmetryOperation &, const Ref< Integral > &)
| Initialize the ShellRotation for solid harmonic functions, given the angular momentum, a symmetry operation, and an Integral object.
| ShellRotation (int n)
| Initialize this ShellRotation to hold a n by n transformation.
| ShellRotation (const ShellRotation &)
| Initialize this from another ShellRotation.
| ShellRotation (int a, SymmetryOperation &, const Ref< Integral > &, int pure=0)
| Initialize using init(...) or, if pure is nonzero, init_pure(...).
virtual | ~ShellRotation ()
ShellRotation & | operator= (const ShellRotation &)
| Assign this to another shell rotation.
int | am () const
| Return the angular momentum.
int | dim () const
| Return the number of functions in a shell.
double & | operator() (int i, int j)
| Return an element of the transform matrix.
double * | operator[] (int i)
| Return a row of the transform matrix.
ShellRotation | operate (const ShellRotation &rot) const
| Returns the result of rot*this.
ShellRotation | transform (const ShellRotation &rot) const
| Returns the result of rot*this*transpose(rot).
double | trace () const
| Return the trace of the transformation.
void | print () const
| Print the object to ExEnv::out0().
