2D plot by including third parameter as colorbar
显示 更早的评论
I have 3 matrices (X Y and Z). Among these X and Z are of same size, that means same number of rows and columns. the second one Y is a column vector with same number of rows of X and Z. I need to create a plot between these three.The x axis will be matrix X and y axis will be vector Y. The values in Z matrix corresponding to X and Y matrix is represented in the plot and the values should show as colorbar.
Can anyone help please? I will be so grateful.

The simplest way to doing this is by using the 'surf' or 'contourf' functions.
But, for that you need to create m x n matrix for all three variables. First convert Y from column to Row and then use 'meshgrid' comand to create Y as same size as X.
Y=Y';
Y=meshgrid(Y);
Y=Y(length(X),:);
Then use countourf
contourf(X,Y,Z)
