This example shows how to display a two-dimensional layer with 40 neurons arranged in an 8-by-5 triangular grid. 

pos = tritop([8 5]);
plotsom(pos)

Figure contains an axes object. The axes object with title Neuron Positions, xlabel position(1,i), ylabel position(2,i) contains 2 objects of type line. One or more of the lines displays its values using only markers
