bracketmatch

check and find unmatched parentheses brackets and braces () [] {} in a file

It displays the unmatched brackets and the corresponding line numbers of the file.

If there is no unmatched brackets, it displays nothing.

Syntax : bracketmatch(fname)

The input fname should be a string of the file path and file name or just the file name if the file is in the same folder as the file bracketmatch.m

Please do not forget to include the quote symbol and file extension as input fname.

for example: bracketmatch('bracketmatch.m')

It displays: unmatched ')' at line: 12

Because the unmatched parenthesis is an ASCII char, and does not have a match.

The algorithm is from college level course Data Structure, chapter Stack.
