Member Function Documentation

◆ __eq__()

bool SymEngine::MatrixMul::__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 23 of file matrix_mul.cpp.

24 {
25  if (is_a<MatrixMul>(o)) {
26  const MatrixMul &other = down_cast<const MatrixMul &>(o);
27  if (!eq(*scalar_, *other.scalar_)) {
28  return false;
29  }
30  return unified_eq(factors_, other.factors_);
31  }
32  return false;
33 }
bool eq(const Basic &a, const Basic &b)
Checks equality for a and b
Definition: basic-inl.h:21

◆ __hash__()

hash_t SymEngine::MatrixMul::__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 13 of file matrix_mul.cpp.

14 {
15  hash_t seed = SYMENGINE_MATRIXMUL;
16  hash_combine<Basic>(seed, *scalar_);
17  for (const auto &a : factors_) {
18  hash_combine<Basic>(seed, *a);
19  }
20  return seed;
21 }

◆ compare()

int SymEngine::MatrixMul::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 35 of file matrix_mul.cpp.

36 {
37  SYMENGINE_ASSERT(is_a<MatrixMul>(o));
38  const MatrixMul &other = down_cast<const MatrixMul &>(o);
39  int cmp_scalar = scalar_->compare(*other.scalar_);
40  if (cmp_scalar != 0) {
41  return cmp_scalar;
42  }
43  return unified_compare(factors_, other.factors_);
44 }
int unified_compare(const T &a, const T &b)
