Delete a cell array column

Question

Placed simple values into the cell array for testing.

model{1,1}=1;model{1,2}=2;model{1,3}=3;
model{2,1}=4;model{2,2}=5;model{2,3}=6;
i=2;//I want to remove the second column

temp={  model{:,1:i-1} model{:,i+1:size(model,2)}  }

I wanted a result like this:

temp =

[1]    [3]    
[4]    [6]

But I'm getting this:

temp =

[1]    [4]    [3]    [6]

How can I get this right?

p.s: for anyone working on Cell Arrays, there's a nice technique for appending here.

You can reshape or delete the cells themselves using ()-addressing.

model(:,2) = [];

there is a function called fun_removecellrowcols, which removes specific row/columns indicated by the user. This affects the dimensions of the cell, due to the row/cols removal.

You have to transpose the two pieces, and change some parentheses:

temp= [{ model{:,1:i-1}}' {model{:,i+1:size(model,2)}}']

that doesn't work if you have more than one column before or after the one to remove – Diederick C. Niehorster Jan 07 '14 at 10:16
