vector of Lagrange multipliers.
lagr(1:n)
is the Lagrange vector
associated with the bound constraints and lagr (n+1
: $)
is the Lagrange vector associated with the
linear constraints. (If an upper-bound (resp. lower-bound)
constraint i
is active
lagr(i)
is > 0 (resp. <0).
integer, return the execution status instead of sending errors.
info==1 : Too many iterations needed
info==2 : Accuracy insufficient to statisfy convergence criterion
info==5 : Length of working array is too short
info==10: The constraints are inconsistent
The sifqld
function decodes, compile,
link the given problem, check if fits the
qld
scope, and finally call the Scilab function
qld
in order to solve the given problem.
