I have a large cell array of strings I am trying to convert to numeric data
> whos tt
Name Size Bytes Class Attributes
tt 8634370x1 6147671440 cell
tt(1)
ans =
{1x5 cell}
tt{1}
ans =
'2017' '058' '19' '24' '01.052261'
I am trying to convert this into a matrix of 8634370x5 using str2num or eval. I am lost in cell array indexing. Any help is greatly appreciated. Thanks.

cellfun(@str2num, tt)
will do the trick, cellfun applies str2num to every cell.

+1 very nice. I think str2double would be more robust:
cellfun(@str2double, tt)

Cool, will keep str2double in mind!
