How to use a for loop using contourfmap method ?

Hello,

I used the contourfcmap and I directly chose the number of levels I want, unfortunately I'm struggling to do a loop of 100 images using this method ! anyone can help me please?

To explain the problem, I have 100 matrices in a folder (each matrix is an image that I want to contourfmap) and after that save them in a folder as images with the colors I chose in contourfmap. Is this possible ?

This is my code:

for i = 1:N
    %names is the char name of all matrices
    if i < 10
        names(i,:) = strcat("X_t0000",string(i),".mat");
    else
        names(i,:) = strcat("X_t000",string(i),".mat");
    end 
    % A = eval(names);%(i,:)) ;
    %After that I didn't know how to use names so I change to this follows:
    Data= load(F(i).name);
    z=Data.data; %iside each matrix there is matrix named 'data'
    h1 = contourfcmap(v,x,z,[0.1 0.33],jet(1),[.1 .1 .1], [.9 .9 .9], 'eastoutside')
    d = h1.c
    l=h1.h
    export_fig(fullfile(Folder, sprintf('%05d.png', i)))
    
    %%% Here I had only one image appeared I think the last one.
   % imwrite(d,fullfile(Folder, sprintf('%05d.png', i)))
   
   % A = cat(3,names); %Here I wanted to concatenate the 100 matrices into
   % one like 2048x2048x100 but I didn't succed 
end

If it isn't clear please tell me to explain more. Thank you in advance.
