t test ( not sure if my implementation is correct)

Suppose that I have two groups, N and R. Each group contains four columns which represent different subjects. For example (hypothetically):

N1 = [1:5]' .... N4 = [1:5]' so that N = { N1,N2,N3,N4}

R1 = [1:5]'.... R4 = [1:5]' so that R = {R1...R4}

Is it possible to enable a loop which which can perform the t-test so that I can avoid this manually:

h = ttest(N1,R1);

.

.

.

h = ttest(N1,R4);

---

h = ttest(N2,R1);

.

.

.

h = ttest(N2,R4); and so on

I understand it may be wrong my implementation of the t-test. But I would like to put into a loop what I just described. Any guidance and help will be appreciated.

N=randi(100,5,4);%your matrix;
R=randi(100,5,4);%your matrix
h=1;
for n=1:4
    for r=1:4
       H(h)=ttest(N(:,n),R(:,r));
       h=h+1;
    end
end
H

H = 1×16

0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0

wow thank you

By any chance, do you know how I can display the columns from N and R which h = 1?
