CL_oe_cireq2kep

Description

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

  The transformation jacobian is optionally computed.

  See Orbital elements for more details

Parameters

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

kep:

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

jacob:

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

Examples

// Example 1 cireq = [7000.e3; -7e-3; 1e-4; 1e-4; -2e-3; 3]; kep = CL_oe_cireq2kep(cireq); // Example 2 cireq = [7000.e3; -7e-3; 1e-4; 1e-4; -2e-3; 3]; [kep,jacob1] = CL_oe_cireq2kep(cireq); [cireq2,jacob2] = CL_oe_kep2cireq(kep); cireq - cireq2 // zero jacob1*jacob2 // identity
