How do I plot a function with multiple outputs?

I am trying to create a function that will plot with the following parameters:

[VVectA3,VVectB3] = rwAB(10,0,0,0.3,0.3,1);

figure;

plot(VVectA3)

hold on

plot(VVectB3)

plot(VVectA3+VVectB3)

For my rwAB function this is what I did:

function [VvectA,VvectB]=rwAB(nTrials,VA,VB,alphaA,alphaB,lambda)

VVectA = VA;

VVectB = VB;

for i = 1:nTrials

VA = rwABRule(VA,alphaA,lambda)

VB = rwABRule(VB,alphaA,lambda)

VVectA = [VVectA VA]

VVectB = [VVectB VB];

end

end

Furthermore, for the function rwABRule that is within my rwAB function I did this:

[VA,VB]=rwABRule(VA,VB,alphaA,alphaB,lambda)

function [VA,VB]=rwABRule(VA,VB,alphaA,alphaB,lambda)

VA = VA + alphaA*(lambda-VA)

VB = VA + alphaB*(lambda-VB)

end

However, when I try to plot it I am given these three errors:

Error:

Local function name must be different from the script name.

Error:

VA = rwABRule(VA,alphaA,lambda)

Error:

[VVectA3,VVectB3] = rwAB(10,0,0,0.3,0.3,1)

So I know that there is something wrong with either my rwABRule function or my rwAB function or both but I can not figure out what I am doing wrong. I thought I was creating my function correctly but I guess not. Any help would be greatly appreciated.

You are calling the function rwABRule incorrectly.

Also, there's a spelling mistake in your function call.

[VVectA3,VVectB3] = rwAB(10,0,0,0.3,0.3,1);
figure;
plot(VVectA3)
hold on
plot(VVectB3)
plot(VVectA3+VVectB3)

function [VVectA,VVectB]=rwAB(nTrials,VA,VB,alphaA,alphaB,lambda)
 %capital V^
    VVectA = VA;
    VVectB = VB;
    for i = 1:nTrials
        [VA,VB] = rwABRule(VA,VB,alphaA,alphaB,lambda);
        %corrected function call
        VVectA = [VVectA VA];
        VVectB = [VVectB VB];
    end
end

function [VA,VB]=rwABRule(VA,VB,alphaA,alphaB,lambda)
    VA = VA + alphaA*(lambda-VA);
    VB = VA + alphaB*(lambda-VB);
end

Thank you so much!

You are welcome!

One more thing? How would I make the plot go up to only 1 and not 2?

[Gabriel]

And is it possible to change the colors of each of the three plots on the figure?

[Dyuman Joshi]

%y limit
ylim([0 1])


%color
plot(VVectA3, 'r')
plot(VVectB3, 'b')
plot(VVectA3+VVectB3, 'k')

You can choose color of your choice

Thanks again!
