Hi! I get an error for folowing line of code: "file_a = substring(char(file_a), 0, findstr(char(file_a), '_')-2);". Matlab returns an error: "??? Undefined function or method 'substring' for input arguments of type 'char'.". There is no substring function in matlab... How did you solve this ? PLIZ
This function is not useful for other. This script does not contain any comments and for running it a specific MAT file required, which is not included in the submission. The code is not efficient, so e.g. MLint shows a hint for an improvements already. Therefore my opinion is: Neither useful nor usable.
Geoff: The functionality you seek is available in circles.m, which is described here: http://www.mathworks.com/matlabcentral/fileexchange/45952-circle-plotter/content/circles_demo/html/circles_documentation.html
