Can anyone help me with the "Axis rotation sequence for the Euler angles"

I need the information for the eul2rotm of "XYX"

I couldnt find this even on matlab documentation

[Jan]

What does "the information for the eul2rotm of "XYX"" mean? Which problem do you want to solve?

[Chaitanya Mulla]

I need to solve the problem having the order of rotation angles which is x-axis,

y-axis, x-axis (i.e., XYX) using eul2rotm. hope this helps

It is still not clear. Do you want to obtain the rotation matrix for and input of 3 angles and the order XYX?

eul2rotm uses ZYX, ZYZ and XYZ only. So if you really want to get XYX with eul2rotm the answer is: This does not work.

The rotation matrix for the Euler angles in the order XYX is:

s1 = sin(alpha);
c1 = cos(alpha);
s2 = sin(beta);
c2 = cos(beta);
s3 = sin(gamma);
c3 = cos(gamma);

[c2,      s2.*s1,            -s2.*c1; ...
 s3.*s2,  c3.*c1-s3.*c2.*s1,  c3.*s1+s3.*c2.*c1; ...
 c3.*s2, -s3.*c1-c3.*c2.*s1, -s3.*s1+c3.*c2.*c1];
