    Undergrad At what altitude and velocity is an orbit geosynchronous?

    The general equation for the orbital period of a satellite in orbit around the Earth: T=2*pi*sqrt(a3/muE) With a equal to the semi-major axis of the orbit (which is the radius r in a circular orbit). The gravitational paramter of the Earth is called muE, and it has the following value...

    MATLAB MatLab: How to add a matrix to a structure without a loop?

    The AA.BB structure is called spacecraft .model in my own simulation. It will be a 1x1000 structure with the following fields: [FONT="Courier New"]time meanJulianDate position velocity I have the following matrices: [FONT="Courier New"]t [1000x1] MJD [1000x1] r [1000x3] V...

    MATLAB MatLab: How to add a matrix to a structure without a loop?

    I know the command .*, but don't think it is really what I need. I need to copy the matrix I have into a structure, but it gives errors, which I will post later in this message. I have this structure AA.BB. This BB has to go from 1 to 1000, which are indications for time steps in a...

    MATLAB MatLab: How to add a matrix to a structure without a loop?

    Hi, I have a structure AA.BB, which goes from AA.BB(1) to AA.BB(1000). I have for example a matrix "X" of size [1000x3], which I want to add to this structure, such that it becomes like this: AA.BB(1).X(1) AA.BB(2).X(1) ... AA.BB(1000).X(1) I want the same for X(2) and X(3). Can...
