Detailed Description

template<int M, int N, class ELT, int CS, int RS>
class SimTK::Mat< M, N, ELT, CS, RS >

This class represents a small matrix whose size is known at compile time, containing elements of any Composite Numerical Type (CNT) and engineered to have no runtime overhead whatsoever.

Memory layout defaults to packed, column ordered storage but can be specified to have any regular row and column spacing. A Mat object is itself a Composite Numerical Type and can thus be the element type for other matrix and vector types.

Template Parameters

M	The number of rows in this matrix (no default).
N	The number of columns in this matrix (no default).
ELT	The element type; default is Real.
CS	Column spacing in memory as a multiple of element size (default M).
RS	Row spacing in memory as a multiple of element size (default 1).

Constructor & Destructor Documentation

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( )

inline

Default construction initializes to NaN when debugging but is left uninitialized otherwise to ensure that there is no overhead.

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const Mat< M, N, ELT, CS, RS > &  src )

inline

Copy constructor copies only the elements that are present and does not touch any unused memory space between them if they are not packed.

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const SymMat< M, ELT > &  src )

inlineexplicit

Explicit construction of a Mat from a SymMat (symmetric/Hermitian matrix).

Note that a SymMat is a Hermitian matrix when the elements are complex, so in that case the resulting Mat's upper triangle values are complex conjugates of the lower triangle ones.

template<int CSS, int RSS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const Mat< M, N, E, CSS, RSS > &  src )

inline

This provides an implicit conversion from a Mat of the same dimensions and element type but with different element spacing.

Template Parameters

CSS	Column spacing of the source Mat.
RSS	Row spacing of the source Mat.

template<int M, int N, class ELT, int CS, int RS>

template<int CSS, int RSS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const Mat< M, N, ENeg, CSS, RSS > &  src )

inline

This provides an implicit conversion from a Mat of the same dimensions and negated element type, possibly with different element spacing.

Template Parameters

CSS	Column spacing of the source Mat.
RSS	Row spacing of the source Mat.

template<int M, int N, class ELT, int CS, int RS>

template<class EE , int CSS, int RSS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const Mat< M, N, EE, CSS, RSS > &  mm )

inlineexplicit

Explicit construction of a Mat from a source Mat of the same dimensions and an assignment-compatible element type, with any element spacing allowed.

Template Parameters

EE	The element type of the source Mat; must be assignment compatible with element type E of this Mat.
CSS	Column spacing of the source Mat.
RSS	Row spacing of the source Mat.

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const E &  e )

inlineexplicit

Explicit construction from a single element e of this Mat's element type E sets all the main diagonal elements to e but sets the rest of the elements to zero.

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( const ENeg &  e )

inlineexplicit

Explicit construction from a single element e whose type is negator<E> (abbreviated ENeg here) where E is this Mat's element type sets all the main diagonal elements to e but sets the rest of the elements to zero.

template<int M, int N, class ELT, int CS, int RS>

SimTK::Mat< M, N, ELT, CS, RS >::Mat ( int  i )

inlineexplicit

Explicit construction from an int value means we convert the int into an object of this Mat's element type E, and then apply the single-element constructor above which sets the Mat to zero except for its main diagonal elements which will all be set to the given value.

To convert an int to an element, we first turn it into the appropriate-precision floating point number, and then call E's constructor that takes a single scalar.

Test whether this is numerically a "scalar" matrix, meaning that it is a diagonal matrix in which each diagonal element is numerically equal to the same scalar, using either a specified tolerance or the matrix's default tolerance (which is always the same or looser than the default tolerance for one of its elements).

bool SimTK::Mat< M, N, ELT, CS, RS >::isNumericallySymmetric ( double  tol = getDefaultTolerance() ) const

inline

A Matrix is symmetric (actually Hermitian) if it is square and each element (i,j) is the Hermitian transpose of element (j,i).

Here we are testing for numerical symmetry, meaning that the symmetry condition is satisified to within a tolerance (supplied or default). This is a relatively expensive test since all elements must be examined but can be very useful in Debug mode to check assumptions.

template<int M, int N, class ELT, int CS, int RS>

bool SimTK::Mat< M, N, ELT, CS, RS >::isExactlySymmetric ( ) const

inline

A Matrix is symmetric (actually Hermitian) if it is square and each element (i,j) is the Hermitian (conjugate) transpose of element (j,i).

This method tests for exact (bitwise) equality and is too stringent for most purposes; don't use it unless you know that the corresponding elements should be bitwise conjugates, typically because you put them there directly.
