Convert cell array to numeric data

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)

[Alexandra Harkai]

Cool, will keep str2double in mind!
