1 Description

This factor specifies the frequency

nvar \times nps_p_foas_rsrtfct

with which the CG/LCG directions are replaced by the steepest descent direction (

d_{k} = - g_{k}

)

Used by: nps_p_foas_rsrtfct in e04kff.

CommE04RA::setter_nps_p_foas_rsrtfct returns a reference to the communication class itself.
