paramagpy.metal.euler_to_matrix(eulers)[source]¶

Calculate a rotation matrix from euler angles using ZYZ convention

Parameters: eulers (array of floats) – the euler angles [alpha,beta,gamma] in radians by ZYZ convention.
Returns: matrix – the rotation matrix
Return type: 3x3 numpy ndarray

Examples

>>> eulers = np.array([0.5,1.2,0.8])
>>> euler_to_matrix(eulers)
array([[-0.1223669 , -0.5621374 ,  0.81794125],
       [ 0.75057357,  0.486796  ,  0.44684334],
       [-0.64935788,  0.66860392,  0.36235775]])
