if x = [1 2 3 ...... 10]
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ]
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3]
how can I make save (x,y) and (x,y1) then do load it
then plot it

Try this:
x = 1:10;
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ]
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3]
save('XYvectors.mat','x','y1','y2')
D = load ('XYvectors.mat');
x = D.x;
Y1 = D.y1;
y2 = D.y2;
Use whatever file name you want.
See the documentation for the plot function.

There are certainly different ways to do so.
E.g.:
x = 1:1:10;
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ];
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3];
save('filename', 'x', 'y1', 'y2') ;
data = load('filename');
plot(data.x, data.y1);
plot(data.x, data.y2);

But y1, y2 are different results of the operating result when the parameters change so I need to store each one separately and draw them simultaneously

Not sure whether I got your point.
Do you want to know how to plot both traces in one figure or something else?

yes

For plotting multiple traces in one diagram, use the "hold" command in order to prevent the plot from being cleared:
plot(data.x, data.y1);
hold on;
plot(data.x, data.y2);
