how to plot a 3d evenly spaced grid

code is:

clc
clear variables
close all
theta=-pi/6:pi/180:pi/6;
phi=-pi/6:pi/180:pi/6;
[theta,phi]=meshgrid(theta,phi);
for rho=5:0.025:50
    [x,y,z]=sph2cart(theta,phi,rho);
    mesh(x,y,z,'edgecolor','g');
    hold on
    xs=linspace(min(x(:)),max(x(:)),61);
    ys=linspace(min(y(:)),max(y(:)),61);
    zs=linspace(min(z(:)),max(z(:)),61);
end

how to plot xs,ys and zs according to non-uniform spacing grid x,y and z

Question is not clear.....

sir, i made a 3-d grid by meshing of x,y and z..this grid has non-uniform spacing so for better visualizaion, i want to make a uniform spacing grid..for this i took the range of x,y and z..then i used linsapce to make evenly spaced range..sir i plot this range (xs,ys and zs) like

[xs1,ys1]=meshgrid(xs,ys);

[zs1,zs2]=meshgrid(zs);

mesh(xs1,ys1,zs1,'edgecolor','r');

evenly spaced grid has shown but this evenly spaced grid has not been full covering the non-uniform spacing grid..i have tried in many ways but i have not been getting the solution

i mean to say that i want to make a evenly spaced grid which covers the non-uniform grid in 3-d as like as i have done this task ''(gr.jpg)'' in 2-d

I have checked the attached image. Are you looking for change the grid size?

sir , i want to make the uniform grid for non-uniform grid as fully cover the non-uniform grid like i made in 2-d..i dont know it will get by change the grid size..i got the non-uniform grid ''nu.jpg'' and evenly spaced grid ''ev.jpg'' from above given code.. when i hold on both two grids then they are looking as ''cg.jpg''. the green is non-uniform and the red is uniform..
