Latex, Mathematica, and journals
Can anyone tell me why there is no WYSIWYG interface for Latex? Any time I want to publish a paper I have to relearn it again, since I publish rarely. I would gladly use MS Word if the math journals would accept it. And is there any movement to accepting Mathematica output, properly formatted? Steve Gray ... 19 May 2010 20:29

Execute .m file with JLink
We would like to execute a .m file, with JLink against Mathematica Player Pro 7. We are not sure if it is our java code or if the problem is in the .m file. We can execute simple statements directly from the java program with JLink but we get no output from a .m file (we expect the output to be a csv-file writte... 18 May 2010 07:03

Converting colors to height values
The Lunar Orbiter Laser Altimeter has a website http://lro.gsfc.nasa.gov/lola/science.html where jpegs are posted of regions of the moon. I would like to convert the color information to height values. A scale is posted with the images that looks a lot like Rainbow, a ColorFunction. I have Inserted the jpeg of C... 14 May 2010 09:29

Plotting piecewise in 2D
Hi Please take a look at DensityPlot[If[x == 0 && y == 0, 1000, 0], {x, -1, 1}, {y, -1, 1}] This just gives me a uniform plot. Why does the peak at (0,0) not show up? Best, Jimmy. ... 15 May 2010 07:12
