Char matrix.mat

This may be rather easy for some of you. I have a char array with code numbers separated by full stops (see attached) and I want to extract the entire number (including all full stops) and save it in a single cell inside a matrix. I thought that there will be a quick way to do this but could not figure it out properly. Any ideas much appreciated!.

在 MATLAB Online 中打开

Using regexp:

>> C = regexp(TempUid,'\d+\.','match');
>> C{:}
ans = 1.
ans = 3.
ans = 12.
ans = 2.
ans = 1107.
ans = 5.
ans = 2.
ans = 36.
ans = 40299.

Or if you also want to include the trailing number (with no period):

>> C = regexp(TempUid,'\d+\.?','match');
>> C{:}
ans = 1.
ans = 3.
ans = 12.
ans = 2.
ans = 1107.
ans = 5.
ans = 2.
ans = 36.
ans = 40299.
ans = 2014032012122937219119936
