When I run the program I get the error message:
Insufficient number of outputs from right hand side of equal sign to satisfy assignment.
Error in OptikVaglaraUppgift2 (line 78)
[difference minIndex(ii)] = min(diff(:,ii));
The program worked yesterday but when i opened up Matlab again it couldn't run.
Can someone please help me solve the problem and explain what is wrong?
n1 = 1; %utanför linsen
n2 = 1.5; %i linsen
D = 10; %linsens diameter (cm)
R = D./2; %linsens radie (cm)
d = 10; %fokallängd (cm)
lopt = n1*sqrt(d.^2 + R.^2); %Optiska vägen då strålen inte bryts i linsen
Y = linspace(0, R, 1000);
X = linspace(0, d, 1000);
for ii = 1:length(Y)
LoptTemp = zeros(length(Y), length(Y));
L1(:,ii) = sqrt( (d-X).^2 + Y(ii).^2)*n1;
L2(:,ii) = X*n2;
LoptTemp(:,ii) = L1(:,ii) + L2(:,ii);
diff(:,ii) = abs(LoptTemp(:,ii) - lopt);
[difference minIndex(ii)] = min(diff(:,ii));
x_fit(ii) = X(minIndex(ii));
end
figure
plot(x_fit, Y, 'black');
hold on
plot(x_fit.*-1, Y, 'black');
hold on
plot(x_fit, -Y, 'black');
hold on
plot(x_fit.*-1, -Y, 'black');
hold on
ylim([-max(Y)-3, max(Y)+3]);

Let's make sure you haven't written your own min.m function that shadows the built-in min function.
which -all min
If that doesn't resolve the problem, you wrote:
The program worked yesterday but when i opened up Matlab again it couldn't run.
What if anything changed between the last time the program worked yesterday and the first time it failed to work today? Did you install any new toolbox or add-on, did you create any new files, etc.?

Note that clear is not the best option.
It would be best to go back and re-name the offending variable or function to something that does not overshadow any MATLAB functions, and still makes sense in the context of your code.
