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!
