Hello. I have a sufrace like on the image.How can I interpolate z-value (black cross) from this surface? I need the fastest methos (linear, for example)

I'm assuming you have the data for the surface points. If so, I believe interp2 will do what you're asking.

MATLAB: Convert X,Y,Z column data into equally spacing grid of X,Y and corresponding Z

Let X,Y,Z be your data.

N = 500 ;
xi = lisnpace(min(X),max(X),N) ;
yi = lisnpace(min(Y),max(Y),N) ;
[Xi,Yi] = meshgrid(xi,yi) ;
Zi = griddata(X,Y,Z,Xi,Yi) ;

You might try

surf(X, Y, real(Z),'FaceColor','interp','EdgeColor','none');
ylim([0 2])

for starters...
