I have an array of strings in a 4x1 cell format, called textarr, as below:
ExA
ExB
ExC
ExD.exe
I would like to remove the .exe, so I initially tried:
textarr(4) = textarr(4)(1:end-4);
But Matlab did not like the double brackets on the right hand side.
I then tried a method using a temporary variable, like:
lasttemp = textarr(4);
lasttemp = lasttemp(1:end-4);
But this just results in lasttemp becoming a 1x0 cell...
I suspect I am confusing the String itself with elements of a string array. How can I address a String inside a specific element of an array?

If those strings represent filenames then using indexing is not a robust solution (because file extensions do NOT all have three characters!). The simple, robust, easy MATLAB solution to remove the file extensions is to use fileparts.

solution:
textarr={'ExA';
'ExB';
'ExC';
'ExD.exe'}
textarr=strrep(textarr,'.exe','')%remove
