error in rotm2eul stating "NaN/Inf breakpoint hit for validateRotationMatrix.m on line 22. 22 'real','3d','size',[3 3 NaN],varargin{:}}, ..."

rotm = [0 0 1; 0 1 0; -1 0 0];
eulZYX = rotm2eul(rotm)

this test is failing throwing error

Hello @DIleep Kumar,

The error you are encountering typically suggests that the rotation matrix is being rejected as invalid by the "rotm2eul" function, likely because it is not a numerically valid rotation matrix (i.e., its determinant is not 1, or it is not perfectly orthonormal).

After verifying these conditions, it has been confirmed that the matrix in question is indeed a valid rotation matrix.

Additionally, the operation works correctly on my system. I would recommend upgrading your MATLAB installation to the latest version, as this may resolve the issue.

I hope this helps address your concern.

Thanks
