CL_oe_kep2cireq

Description

• Converts classical Keplerian orbital elements to circular equatorial orbital elements.

  The transformation jacobian is optionally computed.

  See Orbital elements for more details

Parameters

kep:

Classical Keplerian orbital elements [sma;ecc;inc;pom;raan;anm] [m,rad] (6xN)

cireq:

Circular equatorial orbital elements [sma;ex;ey;ix;iy;L] [m,rad] (6xN)

jacob:

(optional) transformation jacobian (See Orbital elements for more details) (6x6xN)

Examples

// Example 1 kep = [7000.e3;0.01;1.8;0.1;0.2;0.3]; cireq = CL_oe_kep2cireq(kep); // Example 2 kep = [7000.e3;0.01;1.8;0.1;0.2;0.3]; [cireq,jacob1] = CL_oe_kep2cireq(kep); [kep2,jacob2] = CL_oe_cireq2kep(cireq); kep - kep2 // zero jacob1*jacob2 // identity
