I have a cell array of the sorts:

{'508-647-7000'} {' (508) 647-7001'} {' 617-555-1212'}

I need the special characters and the spaces removed from these. The result should look something like this:

{'5086477000'} {'5086477001'} {'6175551212'}

I tried writing the following cell function to do it:

characters = ['(',')',' ','-'];
s_nos=cellfun(@(x) x~=characters,s_split, 'UniformOutput', false);

but I am getting the following error: * Matrix dimensions must agree.*

Kindly help.

You can enter that solution as an answer and accept it.

You can also use isstrprop to keep only digits:

s_nos=cellfun(@(x) x(isstrprop(x,'digit')),s_split, 'UniformOutput', false);

This worked for me

s_nos=regexprep(s_split,'[^0-9]','');
