Cleans Matlab syntax

17 Dec 2010 (Updated 15 Apr 2011)

Matlab routine (and associated Perl code) which cleans up syntax in Matlab code.

File Information

Description

Matlab-invoked Perl code which cleans up syntax in Matlab code you may have downloaded or inherited:

1) gets rid of trailing commas in "switch", "case", "if and "else" statements.

2) uncrowds mathematical operators and variable names by adding spaces

3) deletes trailing semicolons in "return", "end" and "function" statements.

4) automatically indents code.

Example: clean_Matlab_syntax('C:\Matlab Code\Project\old_m_file.m')

In this example, the code creates a new file named "old_m_file_cleaned.m" in same directory as the target file.

MATLAB release

MATLAB 7.11 (2010b)

26 Jan 2011	Alexandre Gramfort	- the code do not take into account "for" and "elseif" - the code will break if you have something like fprintf(fid, "%d foo bar", 1) % writing stuff to file - a line like this: % or % should not be blanked.
15 Apr 2011	Kevin J. Delaney	You're right--I've attempted to fix these shortcomings in the latest version. Thanks for your comments & please try it again.

Updates
20 Dec 2010	Added automatic indentation. Wrapped Perl code into Matlab function which can be called either on a single .m file or on a whole directory. Allows user to replace existing files.
15 Apr 2011	1) When separating statements & comments, now ignores "%" symbols within quoted strings. 2) More sophisticated indenting scheme.
