I have gathered data from a number of files into a 3-D array A(number of files(or the processor that solved ), Time steps- 80000, Z direction steps per timestep-6). I have actually simplified the calculations by assuming that the concentration points at each z step are equal to y and x. I was thinking of adding an x and y dimension in and combine it with the A array, somehow getting rid of the 1st dimension (number of files). A(timesteps,z,x,y)

That is the array which I would like to plot as it will be the size of (80000*(6*20files)120*120). These will only have concentration values at those points, so how would I be able to plot it over an XYZ coordinate system?

This is what I have for my code so far:

numprocs = 20;
textFilename = cell(1,numprocs);
id = cell(1,numprocs);
tN = 80002;
N = 120;
N2 = N/numprocs + 2;
S= N2 - 2;
A=zeros(numprocs,tN,N/numprocs);
   formatSpec = '%f';
  for k = 1
      textFileName = fullfile('C:\Users\Timmmmeh\Desktop\Project Data',['Processor' num2str(k) '.txt']);
          fid = fopen(textFileName, 'r');
          q = fid;
         m = 0;
          w = 0;
          for ms = 1:80000
               m = m+1;
              w = w+1;
          textData = textscan(fid,formatSpec, S);
           if (isempty(textData{1,1})~= 1)
          for j = 1:S
              A(k,m,j) = textData{1,1}(j,1);
          end
           end
          end
          fclose(fid);
end
dx = 6.35/120;
dy = 5.08/120;
for i = 1:121
        xp(i) = dx*(i-1);
          yp(i) = dy*(i-1);
  end

How you have data? You can simply use pcolor / surf in a loop.

So far I have all my data stored in this matrix: A(k,m,j)

k = file#(1-20),

m - timesteps(80000)

j = (z step size= 6)

I want to combine the k and j because k actually splits the entire z axis (so that I will have 120 concentration points in z axis once i combine them)

Also add x and y concentration dimension.

So essentially I will have this array:

A(80000, 120,120,120)

the last 3 indexes are the z,y,x respectively. Where it will just be the concentration values at each point.

Will this 4-D array work with "pcolor l surf"? I have never heard of this.
