Function Documentation

polarDecompose()

unsigned int polarDecompose	(	const btMatrix3x3 &	a,
		btMatrix3x3 &	u,
		btMatrix3x3 &	h
	)

This functions decomposes the matrix 'a' into two parts: an orthogonal matrix 'u' and a symmetric, positive-definite matrix 'h'.

If the number of iterations returned by this function is equal to btPolarDecomposition::DEFAULT_MAX_ITERATIONS, the algorithm has failed to converge.

Parameters

a	- the original matrix
u	- the resulting orthogonal matrix
h	- the resulting symmetric matrix

Returns

the number of iterations performed by the algorithm.
