How to create variables from table cell array containing char array into separate column

i have table with border coordinates loaded from spreadsheet.

Example data:

testdata = {'POLYGON ((72502 146871.5, 72566 146839.5, 72614 146791.5))';'POLYGON ((64462 138105.5, 65422 139241.5, 65694 139289.5))'};
T = table(testdata);

i want to create two columns variable of x and y from the table say for the first row of T.testdata(1) the output should become:

 x = [72502;72566;72614] and y=[146871.5;146839.5;146791.5]

how can i achieve this? with regexp i manage to strip the unnecessary data

test_regex = regexp(T.testdata{1,1},'[^\(\)]+(?=\))','match');
test_regex{1,1}

ans =

    '72502 146871.5, 72566 146839.5, 72614 146791.5'

I have managed to further solve this by the following step:

newChr = strrep(test_regex{1,1},',',';');
testit = str2num(newChr);
x = testit(:,1)
y = testit(:,2)

but i believe there is more optimised way to do this?
