How can I eliminate all white spaces from the input string and duplicate the resulting string to another in the deblank function, as I am encountering a zsh bus error?

edit

To eliminate all white spaces from a string in MATLAB, you can use the strrep function to replace all occurrences of the space character () with an empty string (''). Here's an example:

str = 'Hello, world! ';
str = strrep(str, ' ', ''); % remove white spaces

To duplicate the resulting string to another variable, you can simply assign it using the = operator:

str2 = str;

If you're encountering a zsh bus error, it may be due to a memory allocation issue or some other problem with your environment. You could try running your code in a different terminal or shell to see if that resolves the issue. Alternatively, you could try running your code on a different machine to eliminate any potential software or hardware issues on your current system.
