For input:
x = {'100614,Peter Beadle,131542'}
You can use regexp to match numerical entries in your cell. The expression below matches numbers from 0-9 for 6 times since the numbers in your cell have exactly 6 digits.
x={'100614,Peter Beadle,131542'};
[tokens,matches] = regexp(x,'[0-9]{6}','match');
x = str2double(tokens{:});
For input:
x = {'100614','Peter Beadle','131542'}
Use the following:
x = {'100614','Peter Beadle','131542'};
x = str2double(x);
x(isnan(x)) = [];

You are welcome. In that case, try using:
x = [8213430049,100573,100614];
x = num2str(x);
x = strsplit(x,' ');
x = str2double(strcat(x{1}(1),'.',x{1}(2:end),x{2}));
x = 8.213430049100573
