Since this flight demonstration, DIDO was used for the International Space Station and other NASA spacecraft. It is also used in other industries. DIDO is also available as a MATLAB "toolbox" product. It does not require the MATLAB Optimization Toolbox or any other third-party software like SNOPT or IPOPT or other nonlinear programming solvers. The MATLAB/DIDO toolbox does not require a "guess" to run the algorithm. This and other distinguishing features have made DIDO a popular tool to solve optimal control problems. The MATLAB optimal control toolbox has been
