assign interpolated color bar value to plot

Code Extract

My code plots the deflection of a cantilever beam. I wish to change the colour of the deflected shape to correspond to associated stress values from the colourmap.

plot3(A(:,1),A(:,2),A(:,3),'k')
hold on

c=colorbar;
set(c, 'ylim', [min(abs(stress)) max(abs(stress))]) 
caxis([min(abs(stress)) max(abs(stress))])

for i = 1:length(stress)

      plot3(A((2*i)-1:2*i,4),A((2*i)-1:2*i,5),A((2*i)-1:2*i,6))
      hold on

end

axis equal

I believe that a solution would involve comparing the stress in the member for the current iteration [stress(i)], with the range of values from the colourmap and subsequently assigning a colour (perhaps in RGB format) that can be included within the plot3 command.

for i = 1:length(stress)

        plot3(A((2*i)-1:2*i,4),A((2*i)-1:2*i,5),A((2*i)-1:2*i,6),'%%INSERT APPROPRIATE COLOURMAP VALUE HERE%%)
        hold on

    end

But I have yet to find a working solution. Any help would be very much appreciated.

Sam!

Note:

• [stress] = [1x4888] matrix corresponding to the shear stress in each member.
• Colormap limits comply with stress values
• for loop plots each member individually (total of 4888)
