p.LineStyle = input('Select which line style you would like: ','s');
while p.LineStyle ~= ('''-''' | '''--''' | ''':''' | '''-.''' | '''none''')
    p.LineStyle = input('Refer to the PDF document for valid inputs: ');
end

I get the error 'Matrix dimensions must agree'

Note that if p is a Mathworks graphics object, then setting p.LineStyle to something invalid would error before getting to the while. That is why I store into a different variable and leave the setting of p.LineStyle until after the input has been validated.

See if the strcmpi (link) function will do what you want.

This works for me:

p.LineStyle = input('Select which line style you would like: ','s');
while ~strcmpi(p.LineStyle, {'''-''' , '''--''' , ''':''' , '''-.''' , '''none'''})
    p.LineStyle = input('Refer to the PDF document for valid inputs: ');
end

You need to make it

input('Refer to the PDF document for valid inputs: ','s')

Check input help page for the reason of parameter 's'.
