## Function Documentation

GLM_FUNC_DECL mat<C, R, T, Q> glm::fliplr | ( | mat< C, R, T, Q > const & | in | ) |

Flips the matrix columns right and left.

From GLM_GTX_matrix_factorisation extension.

GLM_FUNC_DECL mat<C, R, T, Q> glm::flipud | ( | mat< C, R, T, Q > const & | in | ) |

Flips the matrix rows up and down.

From GLM_GTX_matrix_factorisation extension.

GLM_FUNC_DECL void glm::qr_decompose | ( | mat< C, R, T, Q > const & | in | ) |

Performs QR factorisation of a matrix.

Returns 2 matrices, q and r, such that the columns of q are orthonormal and span the same subspace than those of the input matrix, r is an upper triangular matrix, and q*r=in. Given an n-by-m input matrix, q has dimensions min(n,m)-by-m, and r has dimensions n-by-min(n,m).

From GLM_GTX_matrix_factorisation extension.

GLM_FUNC_DECL void glm::rq_decompose | ( | mat< C, R, T, Q > const & | in | ) |

Performs RQ factorisation of a matrix.

Returns 2 matrices, r and q, such that r is an upper triangular matrix, the rows of q are orthonormal and span the same subspace than those of the input matrix, and r*q=in. Note that in the context of RQ factorisation, the diagonal is seen as starting in the lower-right corner of the matrix, instead of the usual upper-left. Given an n-by-m input matrix, r has dimensions min(n,m)-by-m, and q has dimensions n-by-min(n,m).

From GLM_GTX_matrix_factorisation extension.
