`deblank`

Removes trailing whitespace from text.

Syntax

s2 = deblank(s)

Removes trailing spaces, tabs, newlines and null characters.

Only the end of the text is changed; leading and inner whitespace stay. Text made only of blanks becomes empty. To clean both ends use strtrim.

s: Character vector, cell array of character vectors, string array, or char matrix.

s2: Text of the same type, without trailing blanks. For a char matrix, columns that are blank in every row are removed.

['[' deblank('ab   ') ']']
deblank({'a  ','b '})
size(deblank('   '))

Output

ans = '[ab]'
ans = 1×2 cell

    {'a'}    {'b'}
ans = 1×2
