The ability to count the coded lines in a MATLAB file is not directly available in MATLAB. However, you may be able to write a MATLAB file that does this.
An example of such a function is attached to this solution. Alternatively, you may also visit the MATLAB Central web site at the following URL to see if someone else has already tried something similar to what you want to achieve:
For example, you could find:
SLOC: Counts the lines of source code in a MATLAB file.
COUNTCODE : count coded and commented lines in a MATLAB file
