These typedefs provide convenient synonyms for common matrix and vector types.
Note that the typedef name may be used interchangeably with the fully templatized names; they represent exactly the same type.
The simplest names are for types whose elements are of the compile-time default precision type Real which is typically double but can be changed to float at compile time. There are also names prefixed with a lowercase "f" that always use float regardless of the default precision.
Note that there are more template parameters than are specified here; these typedefs are using default values for them. The missing parameters specify the spacing between elements; these typedefs always refer to types for which the elements are packed in memory. See Vec, Row, Mat, SymMat for more information.
For fixed size vectors and matrices, only the 2-, 3-, and 4-element sizes are commonly used. However we provide typedefs for sizes up to 9 in case they are needed. For larger sizes, just use the explicit templatized forms.
| typedef Vector_<Real> SimTK::Vector |
Variable-size column vector of Real elements; abbreviation for Vector_<Real>.
This is the most common large-vector type in the Simbody API and in Simbody user programs.
| typedef Vec<2> SimTK::Vec2 |
This is the most common 2D vector type: a column of 2 Real values stored consecutively in memory (packed).
| typedef Vec<3> SimTK::Vec3 |
This is the most common 3D vector type: a column of 3 Real values stored consecutively in memory (packed).
| typedef Vec<4> SimTK::Vec4 |
This is the most common 4D vector type: a column of 4 Real values stored consecutively in memory (packed).
| typedef Mat<2, 2> SimTK::Mat22 |
This is the most common 2x2 matrix type: two packed columns of 2 Real values each.
The columns have type Vec2 but rows have a stride of 2 so the row type is Row<2,Real,2>, not Row2.
| typedef Mat<3, 3> SimTK::Mat33 |
This is the most common 3x3 matrix type: three packed columns of 3 Real values each.
The columns have type Vec3 but rows have a stride of 3 so the row type is Row<3,Real,3>, not Row3.
| typedef Mat<4, 4> SimTK::Mat44 |
This is the most common 4x4 matrix type: four packed columns of 4 Real values each.
The columns have type Vec4 but rows have a stride of 4 so the row type is Row<4,Real,4>, not Row4.
| typedef SymMat<2> SimTK::SymMat22 |
A compact, 2x2 Real symmetric matrix; only 3 elements are stored.
| typedef SymMat<3> SimTK::SymMat33 |
A compact, 3x3 Real symmetric matrix; only 6 elements are stored.
| typedef SymMat<4> SimTK::SymMat44 |
A compact, 2x2 Real symmetric matrix; only 10 elements are stored.
| typedef Row<2> SimTK::Row2 |
Packed, 2-element row of Real values.
This is the type of a transposed Vec2 and usually does not appear explicitly in user programs.
| typedef Row<3> SimTK::Row3 |
Packed, 3-element row of Real values.
This is the type of a transposed Vec3 and usually does not appear explicitly in user programs.
| typedef Row<4> SimTK::Row4 |
Packed, 4-element row of Real values.
This is the type of a transposed Vec4 and usually does not appear explicitly in user programs.
| typedef Matrix_<Real> SimTK::Matrix |
Variable-size 2D matrix of Real elements; abbreviation for Matrix_<Real>.
This is the most common large-matrix type in the Simbody API and in Simbody user programs.
| typedef RowVector_<Real> SimTK::RowVector |
Variable-size row vector of Real elements; abbreviation for RowVector_<Real>.
This is the type of a transposed Vector and does not usually appear explicitly in the Simbody API or user programs.
