This function is only slightly modified from the original topoplot.m function which is part of EEGLAB. I have used EEGLAB v6.01b while modifying the topoplot function into topoplot_connect. The main purpose is visually summarized in the attached screenshot.
I used the topoplot_connect function while developing a method for isolating transient task-induced networks in the brain at Cognitive Neuroscience Lab, DUKE-NUS Graduate Medical School. The idea can be summarized visually in the graphic included with the script.
