load x,y

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

Answer 1

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

[Timo Dietz]

Not sure whether I got your point.

Do you want to know how to plot both traces in one figure or something else?

[abdullah qasim]

yes

[Timo Dietz]

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);
