I assigned 2 element vectors to a matrix but something is not working.

Hello all,

I need to present a 2D (250 by 150) coordinate system using a matrix. So I assigned the coordinates (2-element vectors) to a matrix using the following code:

for i=0:250
    for j=150:-1:0
        temp = [i,j];
        row = 150-j+1;
        column = i+1;
        Nodes(row, column) = {temp};
    end
end

and obtained a 151x251 cell. But then when I try to indexing a particular element of the matrix

[x,y] = Nodes(1,1);

I am receiving the following error:

Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

because apparently Nodes(1,1) returns [1x2 double].

How can I solve this issue? Thanks.

I am using MATLAB 2016a.

"because apparently Nodes(1,1) returns [1x2 double]."

It does that because that is exactly how you defined it. MATLAB does not just "apparently" do things: bugs aside it just does what you tell it to do and what it is documented to do.

x = Nodes{1,1}(1)
y = Nodes{1,1}(2)

Although you would be better off putting your numeric data into one/two numeric arrays, rather than complicating things with an unnecessary cell array.
