You're replicating the vectors x and y to create a set of matrices X and Y when you use MESHGRID, and since z is still a vector, and not a matrix of the same size as X and Y, you can't plot a mesh. Using the slice() function may help to plot the 3D matrix as slices in a 3D plot. A 3-D plot will consist of an x-y grid with discrete z values for each x-y point. I plot them in the same figure but the contourf plot is automatically at z=0 level. This in turn would plot on the xy plane at 1,2, but would have point at 67. Each z value is associated with an x,y coordinate. I have tried simple things such as: matrix=xlsread(filename); surf(matrix); or matrix=xlsread(filename); X = matrix(:,1); Y = matrix(:,2); [x,y]=meshgrid(X,Y); Z = matrix(:,3); surf (x,y,Z); but here I get the following message: 'Z must be a matrix, not a scalar or vector', Any help with the coding would be appreciated, I am just trying to visualise some results.
