This paper concerns with the numerical evaluation of the variable projection method for quadratic programming problems in three data analysis applications. The three applications give rise to large-scale quadratic programs with remarkable differences in the Hessian definition and/or in the structure of the constraints.

Abstract
This paper concerns with the numerical evaluation of the variable projection method for quadratic programming problems in three data analysis applications. The three applications give rise to large-scale quadratic programs with remarkable differences in the Hessian definition and/or in the structure of the constraints.
