  • xi (float, optional) – Coefficient of XI matrix in exponent.

  • xx (float, optional) – Coefficient of XX matrix in exponent.

  • xy (float, optional) – Coefficient of XY matrix in exponent.

  • xz (float, optional) – Coefficient of XZ matrix in exponent.

  • yi (float, optional) – Coefficient of YI matrix in exponent.

  • yx (float, optional) – Coefficient of YX matrix in exponent.

  • yy (float, optional) – Coefficient of YY matrix in exponent.

  • yz (float, optional) – Coefficient of YZ matrix in exponent.

  • zi (float, optional) – Coefficient of ZI matrix in exponent.

  • zx (float, optional) – Coefficient of ZX matrix in exponent.

  • zy (float, optional) – Coefficient of ZY matrix in exponent.

  • zz (float, optional) – Coefficient of ZZ matrix in exponent.
