You can use plot function,

plot(Array1);
hold on;
plot(Array2);
hold off;

hold will retain current plot when adding new plots.

Error using plot

Invalid data argument.

i was defined array as below :

array = {}

then it being filled by loop

Why are you plotting empty array?

You need to define the array 1st with some elements like,

A = [1 3 4];

then use A into the plot function,

plot(A);

or else you can directly pass the array into the function,

plot([1 3 4]);

To understand plot function in more detail, you can refer the MATLAB documentation of it. (https://in.mathworks.com/help/matlab/ref/plot.html)

no, i dont plotting empty array. the idea is define an empty array then should be filling during function. finally, plot this array after filling.

I guess you are trying to plot cell array as using {}, which is invalid argument in plot function, so you can first covert cell array to vector using or functions, and then try plotting.
