class
SymmetricTensor A symmetric 3x3 tensor represented by 6 values: xx, yy, zz, xy, yz, zx.
Subclassed by SharedMemorySymmetricTensor
Public Functions
-
SymmetricTensor() Constructs a null tensor.
-
SymmetricTensor(const SymmetricTensor &other) Constructs a tensor as a copy of other.
-
SymmetricTensor(double xx, double yy, double zz, double xy, double yz, double zx) Constructs a tensor from the 6 values (xx, yy, zz, xy, yz, zx)
-
SymmetricTensor &
operator=(const SymmetricTensor &SymmetricTensor) Assigns other to this tensor and returns a reference to this tensor.
-
bool
operator==(const SymmetricTensor &rhs) const Returns true if two tensors are equal, otherwise returns false.
An exact match is required xx() == rhs.xx(), etc.
-
bool
operator!=(const SymmetricTensor &rhs) const Returns true if two tensors are not equal, otherwise returns false.
Exact comparison is used (!= between doubles)
-
const SymmetricTensor
operator+(const SymmetricTensor &rhs) const Returns a tensor that is this tensor added with rhs.
-
const SymmetricTensor
operator-(const SymmetricTensor &rhs) const Returns a tensor that is this tensor subtracted with rhs.
-
SymmetricTensor &
operator+=(const SymmetricTensor &rhs) Adds the given rhs tensor to this.
-
SymmetricTensor &
operator-=(const SymmetricTensor &rhs) Subtracts the given rhs tensor from this.
-
const Vec3d
operator*(const Vec3d &v) const Returns a vector that is this tensor multiplied by vector.
-
const SymmetricTensor
operator*(double scalar) const Returns a tensor that is this tensor multiplied by scalar.
-
const SymmetricTensor
operator/(double scalar) const Returns a tensor that is this vector divided by scalar.
-
SymmetricTensor &
operator*=(double scalar) Multiplies every component of this tensor by the given scalar.
-
SymmetricTensor &
operator/=(double scalar) Divides every component of this tensor by the given scalar.
