Hello,

I have a topographic data for three locations in a dataset called all_topo_data(46 by 8). I want to add another column(annual evaporation) into the dataset from a 3 dataset called annual_evaporation_kl, annual_evaporation_manila and annual_evaporation_bangkok which all the dataset contains only 1 by 1 matrix. I wanted to add the data according to variable called location in the all_topo_data dataset.

So..There will be a new column in all_topo_data called annual evaporation which will contains annual evaporation value according to locations.

Thank you

I might not have understood your question, so please let me know if this does not answer it.

Suppose that you have a dataset A of size m x n and between the column 0<i<n and the following column you want to insert a column j from another dataset B. To do that, you just need to do the following

Anew = [ A(:,1:i) B(:,j) A(:,i+1:n)];

Does this solve your problem?

Best regards

Hi Hugo, i tried X=[X; zeros(size(X,1),1)]; and i got the following error Error using dataset/vertcat (line 31) All input arguments must be datasets. Any insight on that? Thank You
