I need to make my_john_sam as mjohsam. I need to remove underscore along with the character present just before underscore.
thanks

Replace any one character followed by one underscore with empty string
>> regexprep( 'my_john_sam', '._', '' )
ans =
mjohsam

>> cssm('my_john_sam')
ans =
mjohsam
>> cssm('a string without underscore')
ans =
a string without underscore
where
function str = cssm( str )
ixs = strfind(str,'_');
for jj = fliplr( ixs )
z = str(jj-1:jj);
str = strrep(str,z,'');
end
end

c='my_john_sam';
idx = c == '_';
c( idx|[idx(2:end), false]) = [];
or
c='my_john_sam';
idx = find(c == '_');
c([idx, idx-1]) = [];
