strtrim

Trims leading and trailing whitespaces from strings, matrices and cell arrays. For matrices, leading and trailing whitespaces are stripped from each row to the size of the longest string in the matrix, to make the length of each row consistent.

R = strtrim('    strtrim Example1   ')

R = strtrim Example1

R = strtrim([' string1234   '; '  string12    '])

R =
string1234
string12

R = strtrim({'123   ', '  example3     '})

R =
{
[1,1] 123
[1,2] example3
}
