Search your entire code and all other m-files in the folder or search path. Use "Find Files" button. Did it find markers2 anywhere else?

You're calling a function, markers2. Since this is not a standard MATLAB function, you should have a file in your directory named 'markers2.m'. If not, this line of code will not work.

If you remove markers2, you can at least plot your data.

scatter(data(1,clusters{cc}), data(2,clusters{cc}))

Consult the documentation for scatter for additional help with other acceptable inputs.
