Description

EV2DCM converts from Euler Vectors (EV) to Direction Cosine Matrix (DCM).

Usage

1
EV2DCM(EV, tol = 10 * .Machine$double.eps, ichk = FALSE, ignoreAllChk = FALSE)

Arguments

EV

Euler Vectors (EV) vector [m1, m2, m3, MU].

tol

Tolerance from deviations from unity for the determinant of rotation matrices or the the vector length for unitary vectors.

ichk

Logical, FALSE=disables near-singularity warnings.

ignoreAllChk

Logical, TRUE=disables all warnings and error checks (use with caution!).

Value

Direction Cosine Matrix (DCM) 3x3xN.
