function [F,V,col] = MarchingCubes(x,y,z,c,iso,colors)
im = dicomread('IM-0001-0001.dcm');
im2 = dicomread('IM-0001-0012.dcm');
im3= dicomread('IM-0001-0079.dcm');
im = im2double(im); % this line to convert from uint16 to double
im2 = im2double(im2);
im3 = im2double(im3);
im = mat2gray(im); % this line to put the data in range [0,1]
im2 = mat2gray(im2);
im3 = mat2gray(im3);
);
c = cat(3,im,im2,im3 );
x
y
z
colors
this is the code i try to run ,sorry if i presented the question the wrong way :(

All that code does is to stack your slices into a volumetric gray scale image, and type out your inputs to the command window. It doesn't do anything like marching cubes.

x, y, z, and colors are inputs to the MarchingCubes routine.
You should be reading the data before you call MarchingCubes.
If your x, y, and z are equally spaced then
[x, y, z] = ndgrid( 1:size(c,1), 1:size(c,2), 1:size(c,3) );
