The Hessian matrix is computed using the interaction matrix, the contact map, and the coordinate differences.
Usage
build.hess(cm, im, deltas)
Arguments
cm
contact map
im
interaction map
deltas
list of difference matrices computed with build.contacts
Details
For a sequence of length n a 3n \times 3n matrix is computed. Only if amino acids are in contact (cm entry equals 1) values for the Hessian matrix are computed as proposed in Hamacher (2006). If amino acids are not in contact their respective matrix entries equal 0. Values for amino acids in contact depend on coordinate differences and interaction strengths.
Value
Return value is the Hessian Matrix.
