Confusion with adding to cell array

I have a cell array with the structure as such,

linesegs = [1x2 double] [1x2 double]

I do some calculations on with some other data that is sent to a function within the current program using a function handle. This results in the following structure within the function.

B = [0 0 1 1];

I want insert this array in the next row of linesegs. Basically B would be split into two cells, one containing [0 0] and the other [1 1].

Everything that I've tried seems to be failing.

linesegs(2,:) = mat2cell(B, 1, [2 2]);

I have actually tried this and I keep getting this error,

Error using mat2cell (line 107) Input arguments, D1 through D2, must sum to each dimension of the input matrix size, [1 1].'

I should also note, that after the calculations are finished in the function the output is returned as a 1x1 cell.

I just figured this out. After the function, I convert the cell to a matrix. Then I convert the matrix back to a cell and I get the format I need.

[1x2 double] [1x2 double]

My function is called by means of a function handle that I created, which points to a function that does the calculations I need. The function handle is called by arrayfun.

[Walter Roberson]

You should consider using cellfun() instead of arrayfun()

Why are you messing around with the complication of a cell array anyway? As I see it, a regular numerical matrix would handle these line segment coordinates just fine, and be a lot simpler.

I will have to post up my program that I'm working on since I am having some more problems with it as well. I well edited this post with the link in a bit.

mathimatical array

could some help me in this issue above

Answer 2

This should work:

 a = {[0 0], [0 0]}
 b = [1 2 3 4]
 a{1} = b(1:2) %choose the first two elements from b and assign to first in a.
 a{2} = b(3:4) %choose third and fourth

Note that is not "the next row".
