Square brackets are a concatenation operator, so this code:

V1 = ['a', 'b', 'c', 'd', '1', '2', '3', '!', '@', '"', '''' ]

is exactly equivalent to (but a pointlessly long and complex way of) simply writing this:

V2 = 'abcd123!@"'''

How to escape single quotes in character vectors is explained in the MATLAB documentation:

https://www.mathworks.com/help/matlab/matlab_prog/represent-text-with-character-and-string-arrays.html#RepresentTextWithCharacterAndStringArraysExample-2

"If the text includes single quotes, use two single quotes within the definition."

You can escape single quotes with another single quote. For sake of clarity, I'm going to transpose the output.

vector = ['a', 'b', 'c','d', '1', '2', '3', '!', '@', '"', '''' ].'
vector = 11×1 char array
    'a'
    'b'
    'c'
    'd'
    '1'
    '2'
    '3'
    '!'
    '@'
    '"'
    '''
