Member Function Documentation

◆ __eq__()

bool SymEngine::ImmutableDenseMatrix::__eq__ ( const Basic o) const

Test equality.

A virtual function for testing the equality of two Basic objects

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

Implements SymEngine::Basic.

Definition at line 20 of file immutable_dense_matrix.cpp.

21 {
22  if (is_a<ImmutableDenseMatrix>(o)) {
23  const ImmutableDenseMatrix &other
24  = down_cast<const ImmutableDenseMatrix &>(o);
25  if (m_ != other.m_ || n_ != other.n_) {
26  return false;
27  }
28  return unified_eq(values_, other.values_);
29  }
30  return false;
31 }

◆ __hash__()

hash_t SymEngine::ImmutableDenseMatrix::__hash__ ( ) const

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

64-bit integer value for the hash

Implements SymEngine::Basic.

Definition at line 9 of file immutable_dense_matrix.cpp.

10 {
12  hash_combine(seed, m_);
13  hash_combine(seed, n_);
14  for (const auto &a : values_) {
15  hash_combine<Basic>(seed, *a);
16  }
17  return seed;
18 }
void hash_combine(hash_t &seed, const T &v)
Definition: basic-inl.h:95

◆ compare()

int SymEngine::ImmutableDenseMatrix::compare ( const Basic o) const

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 33 of file immutable_dense_matrix.cpp.

34 {
35  SYMENGINE_ASSERT(is_a<ImmutableDenseMatrix>(o));
36  const ImmutableDenseMatrix &other
37  = down_cast<const ImmutableDenseMatrix &>(o);
38  if (m_ < other.m_) {
39  return -1;
40  } else if (m_ > other.m_) {
41  return 1;
42  }
43  if (n_ < other.n_) {
44  return -1;
45  } else if (n_ > other.n_) {
46  return 1;
47  }
48  return unified_compare(values_, other.values_);
