Hello, I want to plot a surface, but I have my variables in vector form x=1884x1, y=1884x1 and z=1884x1. This does not fit the dimension that are needed to plot a surface. How can I continue?

Depending on what you want your plot to look like, I would use either scatter3 or plot3.
If your data are in a sense gridded (your x or y vectors have regularly-repeating segments for example) you could use reshape and then use a surface plot.
Without your data or an image, it is not possible to provide a definitive reply.

I have now attached the variabels. I have regularly-repeating segments, but I have never used reshape. I tried sort and then plot, but it still gives problem.

Your data are repeating but not regularly repeating, so reshape is not going to work. They also do not appear to me to be appropriate for a surface plot, since that would require significant interpolation.
I would use stem3 (since that locates each point in Z to particular coordinates on the (X,Y) plane), although scatter3 would work as well:
I1 = load('Søren Schwartz x.mat');
X = I1.MNSv;
I2 = load('Søren Schwartz y.mat');
Y = I2.Tv;
I3 = load('Søren Schwartz z.mat');
Z = I3.Calls;
figure(1)
stem3(X, Y, Z, '.')
grid on
That is likely as close as you can get to a 3D plot with your data.
