Plotting data from three dimensional array

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.

Hello Cameron,I edited my question, sorry for the inconvenience. The length of 2d array and size of 3rd dimension of 3d array is same as shown (21). Still,I get the error.

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