I attached file which contains as this
'10.0.7.4:22->10.0.8.5:26856'
'10.0.13.4:22->10.0.12.5:9997'
'10.0.9.4:22->10.0.10.5:47576'
'10.0.14.4:443->10.0.10.5:4922'
'10.0.14.4:443->10.0.10.5:20113'
'10.0.11.4:80->10.0.13.5:61779'
'10.0.10.4:22->10.0.9.5:64788'
'10.0.9.4:80->10.0.10.5:25283'
I want to take out numbers appears after 1st and 2nd colon in two different variable. i.e. A=[22 22 443 443 80 22 80] and B=[26856 9997 47576 4922....] but A and B should be in column format. how to do it.

There's no point in creating two different variables when it's much easier to have the output as two columns of the same variable. Here's one way to do it:
suffix = regexp(VarName6, '(?<=:)\d+', 'match'); %match sequence of numbers following a :
suffix = str2double(vertcat(suffix{:})) %convert cell array of cell arrays into one big cell array and convert strings to numeric

I'll get you started:
data = [{'10.0.7.4:22->10.0.8.5:26856'};{'10.0.13.4:22->10.0.12.5:9997'}];
result = cellfun(@(x) regexp(x,':[0-9]+','match'),data,'UniformOutput',false);
a = cellfun(@(x) sscanf(x{1},':%d'),result);
b = cellfun(@(x) sscanf(x{2},':%d'),result);
There are other, possibly better, ways.

Well, I'd certainly use captures (tokens in matlab) or look-behind to avoid returning the : as part of the match.
Capture:
regexp(x, ':([0-9]+)', 'tokens')
Look-behind:
regexp(x, '(?<=:)[0-9]+', 'match')
