Public Member Functions | |
| FloatMatrix (const std::vector< std::vector< float > > &matrixIn) | |
| construct from a simple vector<vector<float> > | |
| FloatMatrix (const int64_t &rows, const int64_t &cols) | |
| construct uninitialized with given size | |

| FloatMatrix | transpose () const |
| return the transpose | |
| void | resize (const int64_t rows, const int64_t cols, const bool destructive=false) |
| resize the matrix - keeps contents within bounds unless destructive is true (destructive is faster) | |
| FloatMatrix | getRange (const int64_t firstRow, const int64_t afterLastRow, const int64_t firstCol, const int64_t afterLastCol) const |
| get the range of values from first until one before afterLast, as a new matrix | |
| FloatMatrix | concatHoriz (const FloatMatrix &right) const |
| return a matrix formed by concatenating right to the right of this | |
| FloatMatrix | concatVert (const FloatMatrix &bottom) const |
| returns a matrix formed by concatenating bottom to the bottom of this | |
| void | getDimensions (int64_t &rows, int64_t &cols) const |
| get the dimensions | |
| const std::vector< std::vector< float > > & | getMatrix () const |
| get the matrix as a vector<vector> | |
| void | getAffineVectors (Vector3D &xvec, Vector3D &yvec, Vector3D &zvec, Vector3D &offset) const |
| separate 3x4 or 4x4 into Vector3Ds, throw on wrong dimensions | |
| int64_t | getNumberOfRows () |
| get number of rows | |
| int64_t | getNumberOfColumns () |
| get number of columns | |
Static Public Member Functions | |
| static FloatMatrix | zeros (const int64_t rows, const int64_t cols) |
| return a matrix of zeros | |
| static FloatMatrix | ones (const int64_t rows, const int64_t cols) |
| return a matrix of ones | |
| static FloatMatrix | identity (const int64_t rows) |
| return square identity matrix | |
class for using single precision matrices (insulates other code from the MatrixFunctions templated header) errors will result in a matrix of size 0x0, or an assertion failure if the underlying vector<vector> isn't rectangular
