Matlab-Plotting a probability matrix

Hi,

I would like to produce a scatter plot of the data below. The first column is the x axis and the first row would be y axis. I would like to produce a scatter plott with their respective value. Any help would be appreciated.

Thank you.

Try this:

D = readmatrix('New_MP_CS.csv');
x = D(2:end,1);                                         % Original ‘x’ Vector
y = D(1,2:end);                                         % Original ‘x’ Vector
M = D(2:end,2:end);                                     % Probability Matrix

[r,c] = find(M>0);                                      % Indices Of Non-Zero Probabilities
xv = x(r);                                              % Corresponding ‘x’ Values
yv = y(c);                                              % Corresponding ‘y’ Values
zv = M(M>0);                                            % Corresponding Vector Of Non-Zero Probabilities

figure
stem3(xv, yv, zv, ':.')                                 % Optional, Helps Locate Scatter Points
hold on
scatter3(xv, yv, zv, 5, zv, 'filled')                   % Color Points By ‘z’ Values
hold off
axis([min(x) max(x)    min(y) max(y)  zlim])            % Set Axis Limits
xlabel('x')
ylabel('y')
zlabel('Probability')
