Purpose

Plot self-organizing map neighbor distances

Syntax

```
plotsomnd(net)
```

Description

plotsomnd(net) plots a SOM layer showing neurons as gray-blue patches and their direct neighbor relations with red lines. The neighbor patches are colored from black to yellow to show how close each neuron's weight vector is to its neighbors.

Examples

load iris_dataset
net = newsom(irisInputs,[5 5]);
[net,tr] = train(net,irisInputs);
plotsomnd(net);
