Self organization map (R2018b)

Hi every one,

I use the Matlab R2018b to make SOM map, but I have errors as follows. Please help me about this.

data read ok

>> %% XU LY DU LIEU

>> sD = som_normalize (sD, 'var');

>> sD = som_normalize (sD, 'range');

>> %% HUAN LUYEN DU LIEU

>> sM = som_make (sD);

I had the same errors in my MATLAB 2023b. If anyone using the same toolbox has a solution to this, please help!! aparently it compiles well for my colleague who has v2023a.

that error occurs if you use an old version of the toolbox with r2014b or later. You should get a newer release from https://github.com/ilarinieminen/SOM-Toolbox
