Vertical Headers in TableForm or Grid 1 34 (4/24/2011 12:25:05 PM) comp.soft-sys.math.mathematica Dear all, I would like to create column headers of a table as a vertical text. In fact, the column headers are long but the cell contents are small, so that in this way the table would look better (as normal... ADL

Latin Hypercube and other sampling algorithm 0 48 (2/20/2009 10:45:59 AM) comp.soft-sys.math.mathematica Dear all, I made a search of the Group archive and on the internet, but I could not find examples of Mathematica code for generating efficient multi-dimensional Monte Carlo simulations, like the Latin Hyperc...

How to modify an Excel file 3 36 (1/14/2009 10:33:13 AM) comp.soft-sys.math.mathematica Dear group, I am using Mathematica 6/7 export/import capabilities of Excel files, and they work fine. The only problem is that, as far as I understood, they cannot work with cell formats. This means that I c... ADL

Decimals from the "Get Coordinates" Tool 4 21 (12/20/2008 11:19:50 AM) comp.soft-sys.math.mathematica I have a difficulty with the "Get Coordinate" tool, which can be easily seen with a plot like the following: Plot[Sin[x], {x, 170000, 170005}] When I call the tool and click on the plot, all the x co...

Difficulty in importing dates and times with functions like 2 26 (12/11/2008 8:48:07 AM) comp.soft-sys.math.mathematica Dear group, I have a difficulty in interpreting dates and times with functions like AbsoluteTime. When a date string is in the format that Mathematica understands automatically, the fractions of second are... ADL

Design by Contracts in Mathematica 4 17 (10/31/2008 8:07:05 AM) comp.soft-sys.math.mathematica A question for the experts. I have recently met the concept of Design by Contract (TM) software implementation used in the language Eiffel. It is based on the conditions "require", "ensure" and "invariant"... ADL

Re: How show axes labels with AxesOrigin->{0,0,0} in 3D? #2 12 22 (6/8/2011 11:16:04 AM) comp.soft-sys.math.mathematica Aha! Thanks for spotting that the 3D axes labels are really there. But they're hardly in an optimal position. In 2D, the axes labels are at the ends of the axes. So you'd think, for the sake of Mathemati... murray (1862)

Problem with Simplify and Assumptions 3 30 (5/25/2011 9:57:57 AM) comp.soft-sys.math.mathematica I am wondering how to get the last line to say "True" In[1]:= $Assumptions = {m >= 1, s > 0} Out[1]= {m >= 1, s > 0} In[3]:= Simplify[(1 - 2*m)*s < 0] Out[3]= True In[4]:= Simplify[Exp[(1 - 2*m)*... travlorf (12)

OptionsPattern[...] 2 22 (5/11/2011 8:27:24 AM) comp.soft-sys.math.mathematica This is a question about elegance. For the setups below for funcOne and funcAlpha, you will see the difference in the use of Sequence[...]. funcOne can potentially pass "{ }" to funcTwo, which is undesi... smartin4798 (93)
