Subplot: Subplot divides the current figure into row,column and the figure position.

Plot: plot creates a 2 dimension(X axes vs Y axes) figure or line plot

please check this example:

t=  0:pi/100:2*pi;
x=sin(t);
y=cos(t);
z=x+y;

figure(1)

subplot(3,1,1)  % means divided into 3 row, 1 column and creats into position 1
plot(t,x)       %  a=X values and X is you expected output or Y axes value
subplot(3,1,2) % means divided into 3 row, 1 column and creats into position 2
plot(t,y)
subplot(3,1,3) % means divided into 3 row, 1 column and creats into position 3
plot(t,z)

if you want more please type in the command prompt:
