Detailed Description

symmetric 2x2 matrix Generated from class MR::SymMatrix2d.

Instances created here own their C++ objects, see CppObject.

Constructor & Destructor Documentation

◆ SymMatrix2d() [1/3]

meshlib.SymMatrix2d.SymMatrix2d	(	java.lang.foreign.MemorySegment	ptr,
		boolean	owned,
		java.lang.Object	owner )

Wraps a pointer from the C bindings. If owned, the object is destroyed when the wrapper dies. owner is kept alive as long as this wrapper is. Not for normal use.

◆ SymMatrix2d() [2/3]

◆ SymMatrix2d() [3/3]

meshlib.SymMatrix2d.SymMatrix2d ( meshlib.SymMatrix2d _other )

Generated from constructor MR::SymMatrix2d::SymMatrix2d. The reference to things referred to by the parameter _other (if any) might be preserved in the constructed object.

Calls MR_SymMatrix2d_ConstructFromAnother().
