This is a version for very large arrays where the indices need to be in integer*8 format `set_zero_extra_diag <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/LinearAlgebra.irp.f#L548>`_ Undocumented `sort <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/sort.irp.f_template_184#L161>`_ Sort array x(isize). iorder in input should be (1,2,3,...,isize), and in output contains the new order of the elements. `start_progress <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/progress.irp.f#L1>`_ Starts the progress bar `stop_progress <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/progress.irp.f#L19>`_ Stop the progress bar `svd <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/LinearAlgebra.irp.f#L1>`_ Compute A = U.D.Vt .br LDx : leftmost dimension of x .br Dimsneion of A is m x n .br `u_dot_u <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/util.irp.f#L326>`_ Compute <u|u> `u_dot_v <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/util.irp.f#L299>`_ Compute <u|v> `wall_time <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/util.irp.f#L268>`_ The equivalent of cpu_time, but for the wall time. `write_git_log <http://github.com/LCPQ/quantum_package/tree/master/src/Utils/util.irp.f#L243>`_ Write the last git commit in file iunit.
