isRowConvex -- Row convexity of a collection of cells

Usage:

isRowConvex Q
Inputs:
- Q, a collection of cells
Outputs:
- true if Q is row-convex, otherwise false

Description

Checks whether a collection of cells $\mathcal{P}$ is row-convex, i.e., every pair of cells in the same row determines an inner interval fully contained in $\mathcal{P}$.

i1 : Q = cellCollection {{1,1},{2,1},{3,1},{1,2},{3,2}};

i2 : isRowConvex Q

o2 = false

i3 : Q = cellCollection {{1,1},{1,2},{1,3},{2,3},{2,1}};

i4 : isRowConvex Q

o4 = true
