  When using the convex hull approach in the boundary modeling process,
Model-Based Calibration (MBC) software suites -- such as Model-Based
Calibration Toolbox from MathWorks -- can be computationally intensive
depending on the amount of data modeled. The reason for this is that the
half-space representation of the convex hull is used. We discuss here another
representation of the convex hull, the vertex representation, which proves
capable to reduce the computational cost. Numerical comparisons in this article
are executed in MATLAB by using MBC Toolbox commands, and show that for certain
conditions, the vertex representation outperforms the half-space
representation.
