Remove "square brackets and characters within it" from the string-- Matlab

Question

I have a problem removing the text and special characters from the string. For eg:
str = 'Accleration [ms^{{-}2}]';

The expected output: str_out = 'Acceleration'; I tried using the function regexprep but couldn't get the result as expected.

Which characters should be removed? How can it be identified? — Daniel, Apr 26 '14 at 23:03
The text and characters within square brackets and also the square brackets. — nik, Apr 26 '14 at 23:05

You can try

opens = str == '[';
closes = str == ']';
nestingcount = cumsum(opens - [0 closes(1:end-1)]);
outstr = str(nestingcount == 0);

Note that trimming trailing spaces was not part of your specification, you'll have to do that as well to get your example to work right.
