Hi,

I have code I am trying to run which isnt working anymore. The original version is this:

for p = 1:length(file_list)         
    for c = 1:1                                               
        column_1     = cell2mat(basket_data{p,1}(:,c));
    end
end

Running this with the cell of cells array basket_data worked fine.

Now I am using a cell of doubles array a_basket_h and it no longer works. I am unsure why however.

Here is the code:

for p = 1:length(file_list)                          
    for c = 1:1                                               
        column_2     = cell2mat(a_basket_h{p,1}(:,c));
    end
end

Am I incorrectly indexing the cell of doubles? What do I need to change?

Thank you!

Try removing cell2mat() in the second case:

for p = 1:length(file_list)                          
  for c = 1:1                                               
      column_2     = a_basket_h{p,1}(:,c);
  end
end
