MATLAB: Plotting two(function) curve in same figure?how

MATLABplottingsubplot

can Iam plotting two(function) curve in one figure?how? y1=function y2=function x=1:1:40

plot(x,y1) plot(x,y2)

in same figure? how?

plot(x,y1)
hold on
plot(x,y2)

%or

plot(x,y1,x,y2)

%or

plotyy(x,y1,x,y2)

Use the patch (link) function:

x=0:0.1:10;
y1=exp(-x/2);
y2=exp(-x/3);
figure
hold all
plot(x,y1)
plot(x,y2)
patch([x fliplr(x)], [y1 fliplr(y2)], 'g')
hold off

To use it, create a closed area (the reason for the fliplr calls, since they create the closed area), and choose the color.

%if true
  % code
% end
figure(1)
plot()
...
...
figure(2)
plot()
...
...

Follow this sequence for plotting. There is no legend1. Only legend
