how to add color bar to mesh plot in matlab

Question

I have written below code to show density plot of discrete data and vector field together. The problem is that there is no color bar in mesh plot. I did search to add color bar but I couldn't find any useful solution. Do anyone knows how can one do that?

clear all;
close all;
[x,y] = meshgrid(52:0.001:53,57:0.001:58);
u = (x.*(-1+3.*(y).^2./((x).^2+(y).^2))./(x.^2+(y).^2).^(3/2));
v = v-((y-yy(i)).*(-1+3.*(y).^2./(x).^2+(y).^2))./(x.^2+y.^2).^(3/2));
[curlz,cav]= curl(x,y,u,v);
h=streamslice(x,y,u,v,0.5)
hold on
mesh(x,y,w)

Answer 1

I used the first example since your minimal example had errors.

have you just tried

mesh(x,y,w)
colorbar('southoutside')
