Spectral unmixing and la_least_square_equality [message #41916]

Hello,

Considering three unknowns (a,b,c) and having 7 equations, one
solution for a,b,c can be obtained by using the
la_least_square_equality function.

Two conditions have to be considered:
1) a + b + c = 1
2) (0 ge a le 1), (0 ge b le 1), (0 ge c le 1)
where ge stands for "greater or equal" and le stands for "lower or
equal"

The la_least_square_equality function allows to represent the first
constraint.

But how to represent the second one ?

Thank you,

Francois.
