I want to insert a string in to code:

...

name='time';

filename = 'name_v1.txt';

...

Can the 'time' be inserted in " name_v1.txt"?

ly - if the idea is to replace the 'name' substring within 'name_v1.txt' with 'time', then you could use strrep to accomplish this. For example,

 filename = 'name_v1.txt';
 filename = strrep(filename,'name','time');

would set filename to

 filename =
     time_v1.txt

Or, you could use sprintf to do something similar

 name = 'time';
 filename = sprintf('%s_v1.txt',name);

which would (agains) set filename to 'time_v1.txt'.
