plot same column from different matrices on the same figure

I have 2 matrices A and B both 9x5

I would like to simplify the loop

figure, hold on
for i = 1:5
scatter(A(:,i),B(:,i))
end
hold off

Hi Nicolas,

I understand that you want the same column number in two different matrices be plotted on a figure and then in the next iteration take the data points from the next column in both the matrices and plot them on the same figure?

The loop can be removed when working with PLOT function in MATLAB. PLOT can take matrices as an input argument. More information on the PLOT function can be found in the documentation link below:

PLOT in MATLAB

Scenario 1: Use PLOT function and plot lines:

% Example
  A = rand(9,5); 
  B = rand(9,5);
  figure;
  plot(A,B);

SCATTER function unfortunately does not take matrices as an input argument. So there is no way to remove the loop. More information on SACTTER function can be found in the documentation link below:

SCATTER in MATLAB

But in this case we can specify markers in PLOT function to get the same result:

Scenario 2: Use PLOT function with Markers

% Example with Markers
  A = rand(9,5);
  B = rand(9,5);
  figure;
  plot(A,B,'o');

More information on Markers can be found in the documentation link below: Specify Line Style, Colors and Markers

Hope this helps!

Thanks
