Can I store multiple outputs of a function into a cell?

I am using the function 'ndgrid' to construct a n-dimensional mesh. But I would like to generalize my programme for n-dimensions.

Is there any way where I could store the outputs of the function into a cell, as the number of outputs depends on the number of dimensions.

Something like :

X{:} = ndgrid(x{:})

by the way, x is a cell array containing all the 1-D meshes for each direction. So, in general,

x{i} = linspace(0,1,Nnodes{i})

It sounds like you should look into the function size. I don't really understand what it is that you want to do, so if you could explain a bit more what the code should do, I can see if I can help you further.

Why you want like that? Are you really going to give long dimensions?

[Guillaume]

@Rik, KSSV, this is indeed commonly used with ndgrid when you want to generate the cartesian product of an unknown number of vectors:

function p = cartprod(c)
   %returns the cartesian products of the vectors contained in cell array v
    p = cell(size(c));
    [p{:}] = ndgrid(c{:});
    p = cell2mat(cellfun(@(x) x(:), p, 'UniformOutput', false));
end

Answer 1

x = [{1:10} {1:10}] ;
[I{1:numel(x)}] = ndgrid(x{:}) ;

Your syntax.....works if you make this change:

[X{:}] = ndgrid(x{:})

[Kiran Sagar Kollepara]

your first suggestion works. Not, the second one.

This is bizarre:

 x = [{1:10} {1:10}] ;

Why not simply write this?:

 x = {1:10,1:10};

[KSSV]

@Stephen yes..you are right.. @ Kiran..the second one will not work you are right. I executed it in my pc without clearing variables. So it worked.

[Stephen23]

Your syntax was almost correct, you just need to preallocate the output cell array and use square brackets:

 >> inp = {1:3,4:5,6:7};
 >> out = inp;
 >> [out{:}] = ndgrid(inp{:});
