Member Function Documentation

◆ eq()

bool SymEngine::ImmutableDenseMatrix::__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

o	a constant reference to object to test against

Returns: True if this is equal to o

Implements SymEngine::Basic.

Definition at line 20 of file immutable_dense_matrix.cpp.

{
    if (is_a<ImmutableDenseMatrix>(o)) {
        const ImmutableDenseMatrix &other
            = down_cast<const ImmutableDenseMatrix &>(o);
        if (m_ != other.m_ || n_ != other.n_) {
            return false;
        }
        return unified_eq(values_, other.values_);
    }
    return false;
}

◆ hash()

hash_t SymEngine::ImmutableDenseMatrix::__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 immutable_dense_matrix.cpp.

{
    hash_t seed = SYMENGINE_IMMUTABLEDENSEMATRIX;
    hash_combine(seed, m_);
    hash_combine(seed, n_);
    for (const auto &a : values_) {
        hash_combine<Basic>(seed, *a);
    }
    return seed;
}

◆ accept() [1/2]

void SymEngine::ImmutableDenseMatrix::accept ( EvalRealDoubleVisitorFinal & v ) const

overridevirtual

Implements SymEngine::Basic.

◆ accept() [2/2]

void SymEngine::ImmutableDenseMatrix::accept ( Visitor & v ) const

overridevirtual

Implements SymEngine::Basic.

◆ compare()

int SymEngine::ImmutableDenseMatrix::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.
