i have 2 matrices and want to plot each individual value on a separate graph. like the first value of the first matrix and that of the second matrix only on one graph, then the second values of both on another graph

Please post some example data, along with what you tried. I suspect a call to subplot, simple indexing, and two calls to plot will suffice.

Hello Karelle,
As per my understanding, you have two matrices, say A and B, of the same size. You would like to plot just one (X,Y) pair on a graph for each pair (A(i), B(i)), where i is the index of element in matrix.
From your question, I am not sure whether you would like to have just one figure with multiple subplots for each value pair or have multiple figures with plots for each value pair. Hence I am providing you with a solution for both these mentioned cases.
• One figure with multiple subplots, one subplot for each value pair
a=[1,2,3,4,5;6,7,8,9,10];
b=[2,4,6,8,10;12,14,16,18,20];
%a and b are 2 matrix of same size
sa=size(a);%get the size of a (which is same as b)
for i=1:sa(1)
for j=1:sa(2)
pos=sa(2)*(i-1)+j;%position of current plot in subplot
subplot(sa(1),sa(2),pos);%select the position of subplot among all the subplots
plot(a(i,j),b(i,j),'*');
end
end • Many figures, one figure for each value pair
a=[1,2,3,4,5;6,7,8,9,10];
b=[2,4,6,8,10;12,14,16,18,20];
%a and b are 2 matrix of same size
sa=size(a);%get the size of a (which is same as b)
for i=1:sa(1)
for j=1:sa(2)
figure;
plot(a(i,j),b(i,j),'*');
end
end          I hope this helps resolve the issue you were facing.
