Display just the first letters of a filename as String

2 views (last 30 days)
Hey I wan't to display just the first four letters from the file... lets say: TestFile_18.06.2020.txt so Matlab displays just "Test".
Is there any short possibility to make this happen? It should be integraded into a script later.
Best Regards
Niklas

If it is stored in a variable as a char array, then you can simply use indexing
x = 'TestFile_18.06.2020.txt';
disp(x(1:4))
