Hi
I have some data in a 3x1 struct with 2 fields. The data is stored in this fashion [0.1000,0.2500]. When I retrieve the dat using this code Times_period = S_times(1).Times I get ans = 0.1000 0.2500. I want to retieve exactly this [0.1000,0.2500] (ie with square brackets included). Can anyone advsie how I do this?
I tried Times_period = {"[",S_times(1).Times,"]"}. But I get this = 1×3 cell array {["["]} {1×2 double} {["]"]}
Tried other variations but no success.

They used brackets in that line of code -- [0.1, 0.25] -- because they needed to create an array (a row vector) from two constants. Like Fangjun said, if you already have this array it wants in your S_times(i).Times, then you can just use that:
'timewindow', S_times(i).Times, ...
There are really no brackets - that's just how you construct an array but they are not actually part of the array itself -- the array is just numbers alone.

That makes sense. Thank you!

You can use sprintf() to create a string with any appearance you want.
Or fprintf() to display it with any appearance you want.
