MATLAB: Create multiple spheres at given coordinates using a for loop or function and function call

for loopMATLABmatlab functionmatrix manipulation

Hi I have a set of coordinates that I would like to use to generate spheres on my plot. But I am struggling to write a for loop or function that executes this properly. if working properly i should get 4 new spheres from the coordinates in xyz. I have included the points and my attempt. Any help would be greatly appreciated. 
xyz = [-8.67212090030965	-7.78294481282592	4.19809966191787
4.30363429770975	-6.33796132936349	2.30412196271579
11.4626419696253	3.31049523749869	2.84193335035400
1.28757516363600	6.20802478748340	11.1358580308193]
x1 = xyz(:, 1);
y1 = xyz(:, 2);
z1 = xyz(:, 3); 
SizeXYZ = size(xyz,1);
for i = 1:SizeXYZ
  createspheres(x1(i),y1(i),z1(i));
end
function createspheres(spherex, spherey, spherez)
[spherex, spherey, spherez] = sphere(4);
newroot
end

Best Answer

You can use this code:
xyz = [-8.67212090030965	-7.78294481282592	4.19809966191787
4.30363429770975	-6.33796132936349	2.30412196271579
11.4626419696253	3.31049523749869	2.84193335035400
1.28757516363600	6.20802478748340	11.1358580308193]
x1 = xyz(:, 1);
y1 = xyz(:, 2);
z1 = xyz(:, 3); 
SizeXYZ = size(xyz,1);
for i = 1:SizeXYZ
  [x,y,z] = createspheres(x1(i),y1(i),z1(i));
  surf(x,y,z);
  hold on
end
%
function [X,Y,Z] =createspheres(spherex, spherey, spherez)
[x, y, z] = sphere(20);
X= x+ spherex;
Y = y+ spherey;
Z = z+spherez;
%newroot
end
