Hi all,

I have a strange thing happening with a string. I am reading in a string from a binary file and it puts a blank space at the end of the string. For example, the string would read x='1234567 '. Im trying to remove that last space. I have tried strtrim and x(x~=' ') and regexprep but can remove this space. The problem is probably because strcmp(x(8),' ') returns 0 so this space is somehow not equal to a blank space. If anyone has ever seen this any help would be greatly appreciated.

Thanks

Brendan

PS. I can't just cut off the last space because I don't know if it will always be there so I need to test to make sure its blank.

Does deblank work for you? At least worth a try.

Thanks a bunch. This worked. Its strange that strtrim didn't and this did. But I guess you only need one thing that works

what did x(8)+0 report?

strtrim only deals with white spaces while deblank also takes care of null spaces.
