How can I merge two arrays in adjacent cells?.

I have two different vectors which contain many x-coordinate and y-coordinate in them. I want to merge them in one array where first cells will have x1 and y1-coordinate, second cell will have x2 and y2-coordinate and etc.. I have written a code but it gives different results. It just joins the y coordinates at the point where x-coordinates end.

c_start_x = x_vertices(1:2:end);

c_end_x = x_vertices(2:2:end);

c_start_y = y_vertices(1:2:end);

c_end_y = y_vertices(2:2:end);

c_start = [transpose(c_start_x);transpose(c_start_y)];

I assume that the x and y data is stored in arrays x_vertices and y_vertices respectively.

C = [x_vertices(:) y_vertices(:)]

Here the data will be arranged row-wise, i.e. each coordinate pair will be in the corresponding row.

Hello , thank you for this answer , but this will give me a Nx2 matrix . However, what i want is Nx1 where both x and y are stored in one cell.

Ex - X = [1, 2, 3] and Y = [4, 5, 6]

I want

Z = ([1;4], [2;5], [3;6])

Ok, so you want a cell array. In that case, one approach is -

X = [1 2 3];
Y = [4 5 6];


Z = mat2cell([X;Y], 2, ones(1, numel(X)));

Z{1}

ans = 2×1

1 4

Though, Is there any particular reason why you want to store the data in a cell array?

Generally, storing in a numerical array is quite efficient than storing in a cell array.

X = [1,2,3];
Y = [4,5,6];
C = arrayfun(@horzcat,X,Y, 'uni',0)

C = 1×3 cell array
    {[1 4]}    {[2 5]}    {[3 6]}
