Methods Documentation

add(*args, **kwargs)

Overloaded function.

1. add(self: psi4.core.IntVector, m: int, val: int) -> None

Add to a single element value located at m

2. add(self: psi4.core.IntVector, h: int, m: int, val: int) -> None

Add to a single element value located at m in irrep h

clone(self: psi4.core.IntVector) → psi4.core.IntVector

Clone the vector

copy(self: psi4.core.IntVector, arg0: psi4.core.ProtoIntVector) → None

Copy another vector into this.

dim(self: psi4.core.IntVector, h: int = 0) → int

Returns the number of dimensions per irrep h

dimpi(self: psi4.core.IntVector) → psi4.core.Dimension

Returns the Dimension object

get(*args, **kwargs)

Overloaded function.

1. get(self: psi4.core.IntVector, m: int) -> int

Returns a single element value located at m

2. get(self: psi4.core.IntVector, h: int, m: int) -> int

Returns a single element value located at m in irrep h

get_block(self: psi4.core.IntVector, slice: psi4.core.Slice) → psi4.core.IntVector

Get a vector block

init(self: psi4.core.IntVector, arg0: psi4.core.Dimension) → None

Reallocate the data of the Vector. Consider making a new object.

static iota(arg0: psi4.core.Dimension) → psi4.core.IntVector

nirrep(self: psi4.core.IntVector) → int

Returns the number of irreps

print_out(self: psi4.core.IntVector) → None

Prints the vector to the output file

set(*args, **kwargs)

Overloaded function.

1. set(self: psi4.core.IntVector, m: int, val: int) -> None

Sets a single element value located at m

2. set(self: psi4.core.IntVector, h: int, m: int, val: int) -> None

Sets a single element value located at m in irrep h

set_block(self: psi4.core.IntVector, slice: psi4.core.Slice, block: psi4.core.ProtoIntVector) → None

Set a vector block

zero(self: psi4.core.IntVector) → None

Zeros the vector
