I am trying to calculate Umatrix to visualize the resulting SOM mapping by computing the distances between adjacent neuron by using this equation.

Wk is the weight vector associated with the neuron k. Data dimension is 1865 by 63. But, I am unable to start it without using any toolbox. Is, there any way to do this.
