The meshRatio criterion is the ratio between the
maximimum and the minimum distance between two points of the experimental design.
Usage
meshRatio(design)
Value
A real number equal to the value of the meshRatio criterion for the design.
Arguments
design
a matrix (or a data.frame) representing the design of experiments in the unit cube [0,1]\(^d\). If this last condition is not fulfilled, a transformation into [0,1]\(^{d}\) is applied before the computation of the criteria.

Details
The meshRatio criterion is defined by
$$meshRatio=\frac{\max_{1\leq i \leq n} \gamma_{i}}{\min_{1\leq i \leq n}
\gamma_{i}}$$
where \(\gamma_{i}\) denotes the minimal distance between the point
\(x_{i}\) and the other points of the design.
