After reading the MATLAB 3-D plots topic, you will understand how to create 3-d plots as a surface plot or mesh plot in MATLAB. 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. Learn more about 3d plots, graph What does plot do? How to swap between X, Y and Z in 3D plot . Thanks, Jo. A 3-D plot will consist of an x-y grid with discrete z values for each x-y point. 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.
