Section: String Functions
isspace for a definition of a white-space.
There are two forms for the strtrim function. The first is for
single strings
y = strtrim(strng)
where strng is a string. The second form operates on a cell array
of strings
y = strtrim(cellstr)
and trims each string in the cell array.
strtrim to a simple string
--> strtrim(' lot of blank spaces ');
and here we apply it to a cell array
--> strtrim({' space','enough ',' for ',''})
ans =
[space] [enough] [for] []
