HEX_GRID_DATASET
Generate Hexagonal Grid Datasets

HEX_GRID_DATASET is a MATLAB program which creates a hexagonal grid dataset and writes it to a file.

The program allows the user to choose:

• X1, Y1, the coordinates of the lower left corner of a box;
• X2, Y2, the coordinates of the upper right corner of a box;
• NODES_PER_LAYER, the number of nodes to place in the first layer, from (X1,Y1) to (X2,Y2).
