Plotting data from three dimensional array

32 views (last 30 days)
Hello, I have three dimensional array X of size (10,10,21). I want to plot diagonal elements, i.e X(1,1,:),X(2,2,:) etc over parameter Y=-1:0.1:1. How can I use plot command? When I use plot(Y,X(1,1,:)), I get the error
'Error using plot Data cannot have more than 2 dimensions.'
Thank you for the help.

It’s because your y array is 1x21 and your x is 1x100. Your dimensions don’t match. Make sure your y variable is correct.

plot(y,reshape(x(1,1,:),[1,length(y)]))
