Question

As always I realise this is a simple question but being relatively new to the power of Octave I am struggling to get my head around this. I have a cell array A, which contains vectors. I wish to delete the last two values from each vector and finally append a vector contained within another cell array to each. Here is a minimal example:

A = {[1 2 11 12] [1 2 11 12] [1 2 11 12]}
A = 
{
[1,1] =
      1        2        11        12
[1,2] =
      1        2        11        12
[1,3] =
      1        2        11        12
}
B = {[3 4 5] [3 4 5] [3 4 5]}
B = 
{
[1,1] =
      3        4        5
[1,2] =
      3        4        5
[1,3] =
      3        4        5
}

Thus I want to end up with:

C =
{
[1,1] =
      1        2        3       4       5
[1,2] =
      1        2        3       4       5
[1,3] =
      1        2        3       4       5
}

Any pointers to documentation on this etc. would be great.

Thanks, Matt

Answer 1

use cellfun:

C = cellfun( @(x, y) [x(1:end-2) y], A, B, 'UniformOutput', false);
