Hi,
I'm trying to create an object of the class dataset (Stats toolbox) with a few named "columns". I want such object to initially have no rows. Then, I would like to add new rows one by one. I've tried the code below to create the dataset but I get an error. Can anyone help me with this?
Thanks in advance
P.S. I could not submit this question to the "answers" section of the Mathworks website
% Column names are 'F1' and 'F2'
myDS = dataset([],'VarNames',{'F1','F2'})
??? Error using ==> setvarnames at 23
NEWNAMES must have one name for each variable in A.
Error in ==> dataset.dataset>dataset.dataset at 383
a = setvarnames(a,varnames); % names will be modified to make them valid

myDS =dataset({[],'F1'},{[],'F2'});
Or to see it, myDS =dataset({1,'F1'},{2,'F2'})
