Loop plotting with different linewidth within same figure

I have three 3D matrices(A,B and C) of same size but different values. I want to plot them all in one figure as layers upon each other. Though I want the linewidth to be set specifically for every value being plotted. The code below works fine as long as I define the linewidth myself, but I want it to vary in the figure. Please help.

figure
hold on
for ii = 1:size(A,3)
  plot(A(:,2,ii),A(:,1,ii),'-black');
  plot(B(:,2,ii),B(:,1,ii),'-r','LineWidth',B(:,3,ii));
  plot(C(:,2,ii),C(:,1,ii),'og','LineWidth',C(:,3,ii));
end
hold off

What error are you getting?

Value not a numeric scalar.

'LineWidth' option just accept single number, whereas, in your code, you are passing an array B(:,3,ii) to it. To solve this problem separately define vectors of the width of lines as follow

widthLine2 = 1:size(A,3);  % just an example, you can change it according to thickness you want
widthLine3 = 1:size(A,3);  % just an example, you can change it according to thickness you want
figure
hold on
for ii = 1:size(A,3)
plot(A(:,2,ii),A(:,1,ii),'-black');
plot(B(:,2,ii),B(:,1,ii),'-r','LineWidth', widthLine2(ii));
plot(C(:,2,ii),C(:,1,ii),'og','LineWidth', widthLine3(ii));
end
