Detailed Description

Matrix "outline" refers to the characteristic relationship between the number of rows and columns of a matrix, without necessarily specifying the absolute dimensions.

There are seven possible outline attributes:

  • Rectangular (any m x n)
  • Tall (m >= n)
  • Wide (m <= n)
  • Square (m == n)
  • Column (m x 1)
  • Row (1 x n)
  • Scalar (1 x 1)

A matrix handle with no outline commitment can hold a general (rectangular) matrix, which of course includes all the other outlines as well. Vector handles are always committed to column outline, RowVector handles to row outline. Scalar matrices are also rows, columns, and square and some rows and columns are square (if they are 1x1).

Note that certain outlines imply fixed sizes of one or both dimensions.

Constructor & Destructor Documentation

SimTK::MatrixOutline::MatrixOutline ( )
inline

Default constructor produces an object containing no outline specification.

If used as a commitment it won't accept any outline!

SimTK::MatrixOutline::MatrixOutline ( Outline  outline)
inline

This is an implicit conversion from the Outline enum to a MatrixOutline object.

Member Function Documentation

static const char* SimTK::MatrixOutline::name ( Outline  )
static
std::string SimTK::MatrixOutline::name ( ) const
inline
MatrixOutline& SimTK::MatrixOutline::setToNone ( )
inline

Set the outline back to its default-constructed value of "none".

static OutlineMask SimTK::MatrixOutline::calcMask ( Outline  )
static

Compute a mask of acceptable Outline values given a particular value specified as a commitment.

For example, if the commitment is "Wide" then Square, Row, and Scalar outlines are also acceptable.

Mask SimTK::MatrixOutline::mask ( ) const
inline

When "this" outline is used as a commitment, it represents a mask of acceptable outlines.

Calculate and return that mask.

bool SimTK::MatrixOutline::isSizeOK ( int  m,
int  n 
) const

Determine if the proposed shape satisfies this outline.

void SimTK::MatrixOutline::getMinimumSize ( int &  m,
int &  n 
) const

Return the minimum shape that will satisfy this outline.

static MatrixOutline SimTK::MatrixOutline::calcFromSize ( int  m,
int  n 
)
static

Determine the outline from given actual dimensions.

Outline SimTK::MatrixOutline::getOutline ( ) const
inline

Return the outline value stored in this MatrixOutline object.
