Calculate mean and median when I have 3 variables (axes)

I want to plot a figure, say using the surf function.

I have 3 axes. Error, SNR, and MV

I want to find the median and mean of all my Errors and plot it against SNR and MV values

Question 1: Find means and median when i have 2 other variables/parameters ie SNR and MV

Question 2: Plot.

Thanks in advance.

Error =[0.99, 0.92, 0.45, 0.32, 1.2e-4 ...till the end ]  % Error is a 1x60 data.  
SNR = 10, 30, 50
MV= 0.1:0.2:0.9

I do not understand, what exactly you are asking for.

Error =[ ]  % Error is a 1x60 data. for 5 iterations.

No, Error is the empty matrix. This is no valid Matlab syntax:

SNR = 10, 30, 50

This is not clear also: "that means for every iter there is a snr x mv x error data."

Ok for clarity lets just say Error is a 1x60 matrix. and i want to find the mean of this and plot against SNR and MV values.

i appreciate ur input. but these things dont help me much. im pretty knew to matlab and not so good at programming
