How do I plot a function with multiple outputs?

7 views (last 30 days)
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
