Plot Matrix Matlab at even spaces

I have a matrix A = [1000,1000] and i need to plot it at even spaces

    Ex: The x axis have 1000 spaces from 1 to 1000.
        The y axis have 1000 spaces from 0.5 to 500

the numbers on matrix A represent the position of each point in the z axis

For the first element of A there should be a point

    (1,0.5,{1,1})

and thereafter...

    (1,0.5,{1,1}) (1,1,{1,2}) (1,1.5,{1,3})...
    (2,0.5,{2,1}) (2,1,{2,2}) (2,1.5,{2,3})...
    (3,0.5,{3,1}) (3,1,{3,2}) (3,1.5,{3,3})...

In the end i would have a graphic containing 10^6 points

Is A a cell array?

A = [1000,1000] isn't consistent with the detailed description - or?

Actually i had a cell {1,1000} in which contained 1000 vectors

i transformed it in a matrix because i tought i could plot it that way...

    matrixtaylor = zeros(1000,1000);
    for h=1:1000
        for f=1:1000
            matrixtaylor(h,f) = VarTaylor{1,h}(f);
        end
    end

It seems that the linspace and meshgrid function will do what you want.

"Actually i had a cell {1,1000} in which contained 1000 vectors

    matrixtaylor = zeros(1000,1000);
    for h=1:1000
      for f=1:1000
          matrixtaylor(h,f) = VarTaylor{1,h}(f);
      end
    end

i just need to plot those 1000 vectors o the z plane one next to the other spacing 0.5 from each other..."

i started using matlab recently, could you tell me how do i use meshgrid to do that? i searched and didn`t uderstand

If I understand your ‘A’ cell array correctly, you do not need the for loops to recover your matrix from your cell array. You probably can do it with one call to cell2mat.

For example:

a = randi(10, 10, 15);              % Create Numerical Array
C = mat2cell(a, ones(1,10), 15);    % Convert to (10x1) Cell Of (1x15) Double Vectors
A = cell2mat(C);                    % Create Double Matrix A From C

I would create your x and y matrices as:

x = linspace(1, 1000, 1000);
y = linspace(0.5, 500, 1000);
[X,Y] = meshgrid(x, y);

then use surf or mesh to plot them, such as:

figure(1)
surf(X, Y, A)
grid on

If that does not match up exactly with what you want ‘A’ to be with respect to ‘X’ and ‘Y’, transpose ‘A’:

figure(1)
surf(X, Y, A.')
grid on
