Matlab creates screwed up Postscript files
Hi, I'm not sure whether this is matlab's fault or what... I use Scientific Workplace (a LaTeX front end) and when I save the figure in Matlab as an EPS and import it in LaTeX it shows up just fine in the program and in the resulting dvi viewer. However, when I print the dvi file out of the dvi viewer, whet... 29 Jun 2010 01:59

Differentiating surface composed of isolevels?
Hello, I have a number (12) of isolevels (0 = f(x,y,z = z_i) ) of a surface 0 = f(x,y,z). Now, I want to find dz/dx at the isocurve 0 = f(x = x_a,y,z) for arbitrary x_a. How do I do this? The 12 previously mentioned isolevels are equally spaced and so are the values of y at which the isolevels are specified. So far ... 28 Jun 2010 23:50
