regexp format and using 2 cell arrays

Question

I have a matrix made of 20x cells named T. each cell in this matrix contains the next thing:

1,26:00:01.490, 2.40,101.2,  7.8,-24.0,20.40,-0.76,-0.26

i would like to delimit and split it into columns so i used:

Data=regexp(T,',','split');

The result is that im getting Data = 20x1 cells and inside each cell theres another cell with the splited vector i wanted.

so far its all good but next thing i want to do is to take all of the time variables (26:00:01.490 for example) but they are inside 2 cells. The thing i wanted to do is Data{:,1}{1,2} but it says bad cell reference operation as an error.

someone knows how to take whole column in cell array which is inside another cell?

Answer 1

You can do it by concatenating the data between 1x9 cells by using a combination of vertcat and {:}.

%//First form T
str='1,26:00:01.490, 2.40,101.2,  7.8,-24.0,20.40,-0.76,-0.26';
str=repmat({str},20,1);
Data=regexp(str,',','split');
Data1=vertcat(Data{:});

%//Get your time data in form of cells
timeData_cells=Data1(:,2);

%//Get your time data in form of a matrix
timeData_matrix=vertcat(Data1{:,2}) %//This will work only if all time strings 
                                    %//have the same length.

    '26:00:01.490'
    '26:00:01.490'

timeData_matrix=
    26:00:01.490
    26:00:01.490
