Member Function Documentation

◆ __eq__()

bool SymEngine::DiagonalMatrix::__eq__ ( const Basic o) const
overridevirtual

Test equality.

A virtual function for testing the equality of two Basic objects

Deprecated:
Use eq(const Basic &a, const Basic &b) non-member method
Parameters
oa constant reference to object to test against
Returns
True if this is equal to o

Implements SymEngine::Basic.

Definition at line 17 of file diagonal_matrix.cpp.

18{
20 const DiagonalMatrix &other = down_cast<const DiagonalMatrix &>(o);
21 return unified_eq(diag_, other.diag_);
22 }
23 return false;
24}

◆ __hash__()

hash_t SymEngine::DiagonalMatrix::__hash__ ( ) const
overridevirtual

Calculates the hash of the given SymEngine class. Use Basic.hash() which gives a cached version of the hash.

Returns
64-bit integer value for the hash

Implements SymEngine::Basic.

Definition at line 9 of file diagonal_matrix.cpp.

10{
11 hash_t seed = SYMENGINE_DIAGONALMATRIX;
12 for (const auto &a : diag_)
13 hash_combine<Basic>(seed, *a);
14 return seed;
15}
Basic()
Constructor.
Definition basic.h:120

◆ accept() [1/2]

void SymEngine::DiagonalMatrix::accept ( EvalRealDoubleVisitorFinal v) const
overridevirtual

Implements SymEngine::Basic.

◆ accept() [2/2]

void SymEngine::DiagonalMatrix::accept ( Visitor v) const
overridevirtual

Implements SymEngine::Basic.

◆ compare()

int SymEngine::DiagonalMatrix::compare ( const Basic o) const
overridevirtual

Returns -1, 0, 1 for this < o, this == o, this > o. This method is used when you want to sort things like x+y+z into canonical order. This function assumes that o is the same type as this. Use __cmp__ if you want general comparison.

Implements SymEngine::Basic.

Definition at line 26 of file diagonal_matrix.cpp.

27{
28 SYMENGINE_ASSERT(is_a<DiagonalMatrix>(o));
29 const DiagonalMatrix &other = down_cast<const DiagonalMatrix &>(o);
30 return unified_compare(diag_, other.diag_);
31}
int unified_compare(const T &a, const T &b)
Definition dict.h:205

RCP< const Basic > SymEngine::DiagonalMatrix::get ( size_t  i) const
inline

Definition at line 38 of file diagonal_matrix.h.

39 {
40 return diag_[i];

◆ get_args()

vec_basic SymEngine::DiagonalMatrix::get_args ( ) const
inlineoverridevirtual

Returns the list of arguments.

Implements SymEngine::Basic.

Definition at line 28 of file diagonal_matrix.h.

29 {
