euler2mat and axangle2mat

[joanacfcampos]

I have a questions regarding these two functions.
Consider that I have the following angles e = [0 20 70] (XYZ convention)
When using the function euler2mat I obtain the following rotation matrix (R1):
R1 = [[ 0.32 -0.93 0.17], which then when applied to the vector A = [1 0 0], I obtain A' =[0.32 0.88 -0.34]
[0.88 0.34 0.32]
[-0.34 0 0.93]]

My goal is to find the rotation angles from A to A'.
The cross product of the two vectors is [0 0.34 0.88], which gives me the rotation axis, and the angle between the A and A' is 1.24359 radians.

However, when I apply the function axangle2euler(cross_product, angle) I obtain the following tuple: (-0.24568759842706317, 0.3490658499512599, 1.2217304765563635), which applies a rotation in X.

Is this suppose to happen? And if so, what should I be doing instead?

Thanks a lot
