\returns the size of the storage major dimension, * i.e., the number of columns for a columns major matrix, and the number of rows otherwise */

\sa MapBase::outerStride() */

\returns an estimate of the reciprocal condition number of the matrix of * which \c *this is the Cholesky decomposition. */

\returns the number of transpositions */

\returns the rotation angle in [-pi,pi] */

Save PLY file, given 3D shape (Vx3), and triangle connectivity (Fx3)

PopBack removes and returns the last elements in the queue. Can fail spuriously.

\returns the stored value at index \a key * If the value does not exist, then the value \a defaultValue is returned without any insertion. */

\sa MatrixBase::coeff() * \warning the coordinates must fit into the referenced triangular part */

* Return the pointers to the beginning of each column in \ref valuePtr() */

\returns the kernel of the matrix, also called its null-space. The columns of the returned matrix * will form a basis of the kernel. *

\returns an expression of the matrix U, * The only operation available with this expression is the triangular solve * \code * y = b;

\returns the number of nonzero coefficients which is in practice the number * of stored coefficients. */

\returns the number of non zero coefficients */
