Hello Sir, I want to plot three functions (A,B and C) against z in three seperate figures. Please tell me the possible code.

A=function 1 (y axis)

B=function 2 (y axis)

C= function 3 (y axis )

z on x-axis

Also please tell me , how to create three seperate figures in just one window so that plotts can be seen in one figure but in three different windows of the same one figure. Thankyou for your guidance

Look in the documentation for the function subplot

figure;
subplot(3, 1, 1);
plot(z,A);
subplot(3, 1, 2);
plot(z,B);
subplot(3, 1, 3);
plot(z,C);

if A, B, and C are functions (.m files) rather than variables it may be that the code you should use is

figure;
subplot(3, 1, 1);
fplot(@A,[min(z) max(z])]);
subplot(3, 1, 2);
fplot(@B,[min(z) max(z])]);
subplot(3, 1, 3);
fplot(@C,[min(z) max(z])]);

When you create figures you can do something like this:

fig1 = figure;
fig2 = figure;
fig3 = figure;

Then when you want to plot in a specific figure, lets say figure #2 you do this:

figure(fig2)
plot(x,y)

to plot in multiple axes (matlab-notation for panels to plot in) you have the subplot function, see help and documentation for that function. The elementary use works like this:
