How to remove a bracketed number from a cell array while leaving the number in front of it alone

Hi, I have a cell array called "mycellarray" with the following types of strings in it: 24[13]

The [13] in this case is a reference to a footnote and I want to remove the [13] and just have the number 24 left. How do I use a regular expression to remove "[13]" or any footnote i.e. [3] from the number.

Example of the contents of the cell array

13.4[5]
24[11]
56.99[23]
22[4]

I want to remove all the bracketed values along with the number inside the brackets and just have the double number in front kept in the cell array Thank you for your help.. Bob

mycellarray={'24[13]'}
regexprep(mycellarray, '\[(.*?)\]', '$1') %edited after sir Walter's comment

or

A='13.4[5] 24[11] 56.99[23] 22[4]'
A(A=='[') = [];
% Remove any and all right brackets.
A(A==']') = []

'\[(.*)\]' selects too much if there can be multiple matches in one string. '\[(.*?)\]' would be better.
