Ah..constrOptim is for linear inequality constraints. your ci is a
matrix. it should be a vector.

Hi,
You are right, my intention was to return a set of values and to minimize
them all in a multicriteria optimization problem.
The interesting thing is that when I actually used scalar return of this
function, by minimizing sum of squares in this form:
fr <- function(z) {
t
fr does not return a scalar.

Hello,
I have the following problem:
I have a set of n matrix equations in the form of :

vertical vectors [b0], [b1], ... are GIVEN. We try to estimate

there are many equations (more than cells in matrix A) the system has no
solutions.
