Declaration of nmrPInverseEconomy.

Function Documentation

nmrPInverseEconomy() [1/3]

template<class _matrixOwnerType>

CISSTNETLIB_INTEGER nmrPInverseEconomy ( vctDynamicMatrixBase< _matrixOwnerType, CISSTNETLIB_DOUBLE > & A, nmrPInverseEconomyDynamicData & data )

inline

This function checks for valid input and calls the LAPACK function. The approach behind this defintion of the function is that the user creates a data object from a code wherein it is safe to do memory allocation. This data object is then passed on to this method along with the matrix whose PInverse is to be computed. The data object has members S, U, Vt and PInverse, which can be accessed through calls to method *() along with adequate workspace for LAPACK. This function modifies the contents of matrix A. For details about nature of the data matrices see text above.

Parameters

A	A matrix of size MxN
data	A data object of one of the types corresponding to input matrix

Test

nmrPInverseEconomyTest::TestDynamicColumnMajor nmrPInverseEconomyTest::TestDynamicRowMajor nmrPInverseEconomyTest::TestDynamicColumnMajorUserAlloc nmrPInverseEconomyTest::TestDynamicRowMajorUserAlloc

nmrPInverseEconomy() [2/3]

template<class _matrixOwnerTypeA, class _matrixOwnerTypePInverse>

CISSTNETLIB_INTEGER nmrPInverseEconomy ( vctDynamicMatrixBase< _matrixOwnerTypeA, CISSTNETLIB_DOUBLE > & A, vctDynamicMatrixBase< _matrixOwnerTypePInverse, CISSTNETLIB_DOUBLE > & pInverse )

inline

Basic version of PInverse where user provides the input matrix as well as storage for output. The PInverse method verifies that the size of the data objects matches the input and allocates workspace memory, which is deallocated when the function ends. This function modifies the contents of matrix A. For sizes of other matrices see text above.

Parameters

A	A dynamic matrix of size MxN
pInverse	The output matrices and vector for PInverse

Test

nmrPInverseEconomy() [3/3]

template<class _matrixOwnerTypeA, class _matrixOwnerTypePInverse, class _vectorOwnerTypeWorkspace>

CISSTNETLIB_INTEGER nmrPInverseEconomy ( vctDynamicMatrixBase< _matrixOwnerTypeA, CISSTNETLIB_DOUBLE > & A, vctDynamicMatrixBase< _matrixOwnerTypePInverse, CISSTNETLIB_DOUBLE > & pInverse, vctDynamicVectorBase< _vectorOwnerTypeWorkspace, CISSTNETLIB_DOUBLE > & workspace )

inline

Basic version of PInverse where user provides the input matrix as well as storage for output and workspace needed by LAPACK. No memory allocation is done in this function, user allocates everything including workspace. The PInverse method verifies that the size of the data objects matchesc the input. See static methods in nmrPInverseEconomyDynamicData for helper functions that help determine the min workspace required. This function modifies the contents of matrix A. For sizes of other matrices see text above.

Parameters

A	A dynamic matrix of size MxN
pInverse	The output matrix for PInverse
workspace	The workspace for LAPACK.

Test
