Somthing wrong with SOM Toolbox

Hi, I am working with somtoolbox2_Mar_17_2005 to classify example Iris. As described in instructor, I have input the code as follows:

%make the data

sD = som_read_data('iris.data');

sD = som_normalize(sD, 'var');

%make the SOM

sM = som_make(sD);

sM = som_autolabel(sM, sD, 'vote');

%basic visualization,

som_show(sM,'umat', 'all', 'comp', 1:4, 'empty', 'Labels', 'norm', 'd');

However, there occured a mistake: The double value -1 cannot be converted to a handle

Error som_show (line 497)

h_colorbar(i,1)=-1;

Figure below is the part of som_show function

There isn't actually something wrong with the toolbox (at least with this code snippet). It is just assuming the handle to a colorbar object can be stored in a double, which is not true since R2014b.

You will either have to find/make an updated version of the code or use an older Matlab release.
