How to plot and save the content of a 5D array?

Hello,

I have a 5 dimension array M_ii (attached). It's size is 25x50x3x14x2. I want to plot and save the following on the same figure

M_ii(bb,:,1,1,1)
M_ii(bb,:,2,1,1)
M_ii(bb,:,3,1,1)

And do the same thing for the rest M_ii(:,:,:,pp,ii).

for ii = 1:length(tol)
    for pp = 1:length(p)
        for bb = 1:length(bgt)
            for kk = 1:length(trigger)
                plot(1:length(M_ii(bb,:,kk,pp,ii)),M_ii(bb,:,kk,pp,ii))
            end
            savefig(sprintf('traj.mat'),..)
        end
    end
end

I want to save all the resulting figures as .fig files but without displaying them when I run the code above. For the names of the figures, I want something like this: traj151. Where the first one represents bb=1 and number 5 represents pp=5 and the seconed one represents ii=1

Your help and ideas would be appreciated.

Is your main question how to assemble the file name? I'd use a string array.

n = 1;
p = 42;
q = 999;
filename = "part" + n + "of" + p + "ForUserID" + q + ".txt"

filename = "part1of42ForUserID999.txt"

Or if you need specific formatting, then I'd use sprintf. Note the extra 0 in the display of n in filename2.

filename2 = sprintf("part%02dof%dForUserID%d.txt", n, p, q)

filename2 = "part01of42ForUserID999.txt"

The total number of figures I'm trying to plot should be around 700.

This is what I did so far:

tol = [0.2 0.8]; 
p = 0.05:0.05:0.7;
bgt = 0.01:0.01:0.25;
Trigger = [0.2 0.5 0.8];
figure
for ii = 1:length(tol)
    for pp = 1:length(p)
        for bb = 1:length(bgt)
            for kk = 1:length(Trigger)
                set(gcf,'Visible','off');
                plot(1:length(M_ii(bb,:,kk,pp,ii)),M_ii(bb,:,kk,pp,ii))
            end
            filename = sprintf("bgt%02dp%02dForaID%d.txt", bb, pp, ii);
            savefig('filename.fig')
        end
    end
end

However, when I chose sprintf, it just saves one fig file that cannot be opened.

PS. I attached the mat file of the 5D array if this helps

If you expected this code:

filename = sprintf("bgt%02dp%02dForaID%d.txt", bb, pp, ii);
savefig('filename.fig')

to write to a file whose name is stored in the variable filename, that is not what it does. This code writes to a file whose name is literally filename.fig. If you want to use the contents of the variable as the file name, you need to pass the variable into savefig as an input.

filename = "file1773965.fig";
savefig(filename) % Creates a file named file1773965.fig
savefig('filename') % Creates a file named filename

That savefig(filename) call is equivalent to:

savefig("file1773965.fig")

Thank you so much, Steven.

I'm sorry for my late reply.
