This class is a "CSerializable" wrapper for "CMatrixDynamic<double>".
Definition: CMatrixD.h:23
#define IMPLEMENTS_SERIALIZABLE(class_name, base, NameSpace)
To be added to all CSerializable-classes implementation files.
Virtual base class for "schematic archives" (JSON, XML,...)
#define MRPT_THROW_UNKNOWN_SERIALIZATION_VERSION(__V)
For use in CSerializable implementations.
Definition: exceptions.h:97
This base provides a set of functions for maths stuff.
void serializeFrom(mrpt::serialization::CArchive &in, uint8_t serial_version) override
Serialize CSchemeArchiveBase derived object to CSerializable Object.
Definition: CMatrixD.cpp:33
STORED_TYPE ReadAs()
De-serialize a variable and returns it by value.
Definition: CArchive.h:155
bool fromMatlabStringFormat(const std::string &s, mrpt::optional_ref< std::ostream > dump_errors_here=std::nullopt)
Reads a matrix from a string in Matlab-like format, for example: "[1 0 2; 0 4 -1]" The string must st...
double value_type
The type of the matrix elements.
size_type rows() const
Number of rows in the matrix.
size_type cols() const
Number of columns in the matrix.
#define SCHEMA_DESERIALIZE_DATATYPE_VERSION()
For use inside serializeFrom(CSchemeArchiveBase) methods.
This is the global namespace for all Mobile Robot Programming Toolkit (MRPT) libraries.
Virtual base class for "archives": classes abstracting I/O streams.
Definition: CArchive.h:54
mrpt::vision::TStereoCalibResults out
void setSize(size_t row, size_t col, bool zeroNewElements=false)
Changes the size of matrix, maintaining the previous contents.
std::string inMatlabFormat(const std::size_t decimal_digits=6) const
Exports the matrix as a string compatible with Matlab/Octave.
void serializeTo(mrpt::serialization::CArchive &out) const override
Serialize CSerializable Object to CSchemeArchiveBase derived object.
Definition: CMatrixD.cpp:23
#define SCHEMA_SERIALIZE_DATATYPE_VERSION(ser_version)
For use inside all serializeTo(CSchemeArchiveBase) methods.
size_t ReadBufferFixEndianness(T *ptr, size_t ElementCount)
Reads a sequence of elemental datatypes, taking care of reordering their bytes from the MRPT stream s...
