Hi, this is Amit Vora.
I have a question about Question 5 on Lab 3: When we make the graph of deflection versus distance along the beam, what should the limits of our axes be?

*I'm having trouble getting contour to plot more than the standard number of contour lines. When I use contour(x, y, z), it plots the contour lines fine, but when I specify the number of lines with contour(x, y, z, n), nothing plots. [[User:Jc257|Jc257]] 23:16, 22 September 2009 (EDT)
*:I have had this same problem. I added a colorbar. When I don't give an "n" argument, the color bar ranges from 0 - 300, the range of the surface plot. When I add an "n" argument, the colorbar ranges from 0 - 1 in 0.1 intervals. If this is so, it makes sense that nothing is graphed, because the surface never gets as low as 1, but why would adding more contour lines change this? (I also tried plotting less contour lines - same thing happens.) [[User:Smc41|Smc41]] 09:39, 23 September 2009 (EDT)
** In both cases, the problem is you started with values that make the function go infinite - if you try to use <code>contour</code> with a matrix containing <code>Inf</code>, and then try to specify how many contour lines, MATLAB will become hopelessly confused. Make sure d starts at 1 and theta starts at .1 and you should be able to get multiple contour lines. [[User:DukeEgr93|DukeEgr93]] 13:26, 23 September 2009 (EDT)

*What's the difference between using a meshgrid and using just two linspaces? (ejl23)

Hi this is Everett Loving.
When a logical mask is scanning a matrix of numbers, is it possible to ask the mask to check for two conditions? For example, something like:

variable = (condition && condition) .*value +...
(condition) .....

Hi, this is Everett Loving.
For lab 3, question 5, once the 3 graphs are separated into figures, what is the syntax for inserting them into the emacs file using the epsfig command?

*My favorite demo was the bending truss video. I'm planning on being a civil engineer so that was definitely some cool animation to watch.
