dihedral.m

Computes the dihedral angle between vectors specified by the four sets of atomic coordinates. The atoms are assumed to be bonded as A-B-C-D.

Syntax

    phi=dihedral(A,B,C,D)

Parameters

    A  -  row vector of cartesian coordinates 
          for atom A

    B  -  row vector of cartesian coordinates 
          for atom B

    C  -  row vector of cartesian coordinates 
          for atom C

    D  -  row vector of cartesian coordinates 
          for atom D

Outputs

    phi - dihedral angle, degrees
