I have four matrix A,B,C and D and each of them has a dimension of (56 rows, 4 coulms). I want to scatter the same column of each matrix with another matrix. X1=A(:,1),Y1=B(:,1);X2=A(:,2),Y1=B(:,2), ...,X4=A(:,4),Y4=B(:,4) X5=A(:,1), Y1=C(:,1),X6=A(:,2),Y6=C(:,2),...,Xn=C(:,4), Yn=D(:,4)
I did it for one of them but don't know how to use a loop to make a seperate scatter plot for all of them. I am grateful foe your help.
X1=A(:,1) Y1=C(:,1) scatter(X1,Y1);

Like this?
plot([A,A,A],[B,C,D],'o')
EDIT Based on your comment, here's a new answer:
allX = [A,A,A];
allY = [B,C,D];
for k=1:size(allX,2)
figure(k)
scatter(allX(:,k),allY(:,k))
end

thanks Matt, it's what I wanted.
I have a different labels for X-axises and Y axises. for example:
X1_label='reflectance of instrument A at level 1'
Y1_label='reflectance of instrument B at level 1'
X2_label='reflectance of instrument A at level 2'
Y2_label='reflectance of instrument B at level 2'
.
.
.
label={X1_label;X2_label;...}
I wonder how to put them for different plots?

I found a way to do that.
label={s1;s2;s3;s4;s5;s6;s7;s8;s9;s10;s11;s12;s13;s14;s15;s16}
fignum = 1;
for i=1:4
while ishandle(fignum)
fignum = fignum + 1;
end
figure(fignum);
X=A(:,i)
Y=C(:,i)
scatter(X,Y);
xlabel(s(i));
ylabel(s(i+4));
end
