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

alpha = 0.4363; 
dcm = dcmbody2stability(alpha)
dcm = 3×3

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

alpha = [0.4363 0.1745]; 
dcm = dcmbody2stability(alpha)
dcm = 
dcm(:,:,1) =

    0.9063         0    0.4226

Input Arguments

collapse all

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

Data Types: double

Output Arguments

collapse all

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.
