fsqp solver external function that computes the jacobian of the constraints for CUTEr.
cj=fsqp_grcntr(j,x)
An integer, The index of the constraint for which the gradient is to be evaluated.
A vector, the current value of the unknown
A vector, the current value of the gradient of the jth constraint.
This function computes the gradient of the jth constraint at the point
x
for the current CUTEr problem according to
the fsqp
requirements.
x_is_new
fsqp
x_is_new
Depending on the value returned by x_is_new()
,
this function uses or computes the following global variables
fsqp_cost
, fsqp_grcost
,
fsqp_constr
and
fsqp_grconstr
.
