HI, I have this code and the vector "hrs" is a 200 x 1 double. I cant seem to get the answer I want with this code. How may I debug this? Thank you so much!
If the vector "hrs" is <10, I want 24 to be added to it. if it is > 10, it can remain as it is
if hrs < 10
hrs = hrs + 24;
hrs = hrs;

In MATLAB, you can directly use logical indexing instead of writing a if-block
idx = hrs < 10;
hrs(idx) = hrs(idx) + 24;
In case, you want to see what is wrong with your code, following show how to use if-block with for-loop
for i = 1:numel(hrs)
if hrs(i) < 10
hrs(i) = hrs(i) + 24
hrs(i) = hrs(i);
