How i can program this and how should i build the table? A table is a container that stores column-oriented data in variables. num_lat = splitStr_lat {1,1};%variable that has the numerical value of latitude. The rows of a table can have names, but row names are not required. Consider, for example, tableControl = Based on You can try using data_tr.Var2 {i,1}. hello, having the following tables stored in a cell array, how can we access these tables one by one to extract for example the values of the very first five cells in the first row, use these values to create some knid of an index and store that index in the second column of the cell array? Results_Row_Titles = ShipData(DataIdx-1,:); Look_At_Titles = Results_Row_Titles(1:5,:); % See Matching ShipData Row Titles (Delete). Block Authoring and Simulation Integration. findgroups will return the group index of each row, along with an optional output of all the unique rows. One small suggestion about StarStrider's code: Gert, it would be interesting to hear where these data are coming from, and how they got into MATLAB in that format, if you are able to say.

C = strsplit(T{1}) You can not subscript a table using only one subscript. If there is a match extract the row values and also row-1 which shows the variable names. getDialogControl command to get the custom table handle. It looks like ShipData has what ought to be column headers in every other row, and some rows seem to be out of sync, containing "kinds" of values that other rows do not.
