See if this does what you want:

astr = '2014-06-20T00:00:00-0500';
avct = cellfun(@str2num, regexp(astr, '\d+', 'match'))
avct =
        2014           6          20           0           0           0         500

MATLAB: How to read a string data from excel sheet ? Or to read a single row having charaters

Consider using xlsread. See xlsread for details and pay particular attention to the use of the xlRange input to this function. If you know the number of columns in the file then you could do something like

 [~,txtData]  = xlsread('cycling.xlsx','A1:H1')

In the above, we ignore (using ~) the first output parameter which corresponds to numeric data, and instead concentrate on the text data which is returned as a cell array of strings. We use the range 'A1:H1' to return the data in the first row for columns A through H.

Try the above and see what happens!
