If somebody can tell me how to increase number of lines for fcontour plot I would be much grateful. Thanks in advance.

A somewhat different approach —
syms x y
z(x,y) = exp(-(x-5)^2) + cos(y)
figure
hfc = fcontour(z, [0 10 -2*pi 2*pi]);
colormap(turbo)
title('Default Levels')
figure
hfc = fcontour(z, [0 10 -2*pi 2*pi]);
Lvls = hfc.LevelList;
hfc.LevelList = linspace(min(Lvls), max(Lvls), 5*numel(Lvls));
colormap(turbo)
title('Increased Countours, Same Range')
.

Look at the max and min of your surface, then compute the 'LevelStep' using the number of contours you want. Something like (untested)
numContours = 10;
levelStep = (max(z(:)) - min(z(:))) / numContours;
fcontour(z, 'LevelStep', levelStep);
