12 Jun 2009	simulink matrix element This block outputs a given element of a matrix defined by the raw and the column indices of the elem	Sara Hafeez	hey how is it poosible to create a hex matrix out of this block and can these elements of the block used fo any operation	5
28 Sep 2008	Navigation Coordinate Frame Conversions Converts between navigational coordinate frames	Jason Chiou	The way it converts velocity from ECI to ECEF is wrong. You don't use the same rotation matrix, used for converting position, to convert the velocity. Here is what's in and what's out. >> eci.x = 1; eci.y = 1; eci.z = 1; eci.xdot =10; eci.ydot = 10; eci.zdot = 10; dt =540; ecef = ECI2ECEF( eci, dt) ecef = x: 1.0386 y: 0.9599 z: 1 xdot: 10.3867 ydot: 9.5993 zdot: 10 Obviously, the velocity out is wrong. Take a look at the following page: http://www.constell.org/Downloads/Manual-Version70.pdf	1
29 Nov 2007	Navigation Coordinate Frame Conversions Converts between navigational coordinate frames	Javier Areta	The code is given in a DLL, which from my point of view is a big minus. It would be much more useful (at least from an understanding what's going on point of view) to have it as a script. Perhaps the library call is faster, but it does not help me. Also, some comments on the code would be useful.	2
