delete special characters (\ / : * " < > |) in char

Hi. I need to transform these lines:

name_1 = '<Hello World>';
name_2 ='File numb: 5';

into these:

name_1 = 'Hello World';
name_2 ='File numb 5';

In general, I would like to delete, if they are present, within the name all 8 symbols: \ / : * " < > |

One way:

name_1 = '<Hello World>';

pat=num2cell('\/:*"<>|');

name_1=erase(name_1,pat)

name_1 = 'Hello World'

One way:

name_1 = '<Hello World>';

tf=ismember(name_1, '\/:*"<>|');

name_1(tf)=''

name_1 = 'Hello World'

You could also use regexprep(), though perhaps using erase() is more convenient.

% using numbered variables only makes processing more difficult
% instead of embedding implicit indices in the names, just use an array
names = {'<Hello World>';
         'File numb: 5';
         '1\|2/>3:<4*"5"*6<:7>/8|\9'};

% replace any instance of the listed characters with ''
names = regexprep(names,'[\\/:*"<>|]*','')

names = 3×1 cell array
    {'Hello World'}
    {'File numb 5'}
    {'123456789'  }
