dcmbody2stability

Convert body frame to stability frame transformation matrix

Syntax

dcm = dcmbody2stability(anglesOfAttacks)

Description

dcm = dcmbody2stability(anglesOfAttacks) calculates the direction cosine matrix dcm for given set of angles of attack anglesOfAttacks.

Examples

Determine Direction Cosine Matrix from One Angle of Attack

This example shows how to determine the direction cosine matrix from one angle of attack.

alpha = 0.4363; 
dcm = dcmbody2stability(alpha)

dcm = 3×3

    0.9063         0    0.4226
         0    1.0000         0
   -0.4226         0    0.9063

Determine Direction Cosine Matrix from Multiple Angles of Attacks

This example shows how to determine the direction cosine matrix from multiple angles of attacks.

alpha = [0.4363 0.1745]; 
dcm = dcmbody2stability(alpha)

dcm = 
dcm(:,:,1) =

    0.9063         0    0.4226
         0    1.0000         0
   -0.4226         0    0.9063


dcm(:,:,2) =

    0.9848         0    0.1736
         0    1.0000         0
   -0.1736         0    0.9848

Input Arguments

anglesOfAttacks — Angles of attacks

vector

Angles of attacks, specified as a vector, in radians.

Data Types: double

Output Arguments

dcm — Direction cosine matrices

3-by-3-by-m matrix

Direction cosine matrices, returned as a 3-by-3-by-m matrix, where m is the number of direction cosine matrices. The direction cosine matrix performs the coordinate transformation of a vector in inertial axes to a vector in body axes.
