How to store data result

I want to store this line in variable x so then I can plot it is that possible

x= [dataset1, dataset2] = myfunction(sample1); %I know this doesn't work , but I just wanted to give clear example 
figure

plot(x(:,1) , x(:,2) , 'b.');

What kind of arrays, and how many, do you want your function to return?

sample1 = 1000 and the myfunction is provided by my teacher it long and completed it suppose to generate dataset I know how to plot things but he gave us this line [dataset1, dataset2] = myfunction(sample1) and asked to plot I had an idea that I should run it and then save the data but not sure how to do that

That depends on how you write your function. If you write it as something like this:

function x = myfunction(sample1)
        . . . CALCULATIONS . . .
dataset1 = . . .;
dataset2 = . . .;
x = [dataset1, dataset2];
end

Then ‘x’ would be an (Nx2) matrix that you could then plot as:

figure(1)
plot(x(:,1) , x(:,2) , 'b.')

NOTE — I did not actually test this, but it should work.

so If have these two each one represent dataset should I store them in variable or in new function I'm still a bit confused :/

[traindata, traintarget] = myfunction(sample1); 
[testdata, testtarget] = myfunction(sample2);

[Star Strider]

I apparently misunderstood. If you want ‘x’ to be as you defined it, you need to break it up into two separate statements:

[dataset1, dataset2] = myfunction(sample1);
x = [dataset1, dataset2];

then this will work:

figure(1)
plot(x(:,1) , x(:,2) , 'b.');

The code looks correct. Your ‘myfunction’ could be having problems.
