Hi!, Since I upgrade KDE from 3.2.3 to 3.3, I have no sound. Everything work well, but no sound, I also upgrade arts to arts-1.3.0,1 and also have 80process for arts, what wrong ?

HoldForm[] is loosing the 1* when it apparently should not: In[1]:= HoldForm[1*2*3] Out[1]= 2 x 3 In[2]:= HoldForm[1*1*1] Out[2]= 1 x 1 x 1 In[3]:= HoldForm[3*2*1] Out[3]= 3 x 2 In[4]:= HoldForm[2*2*2] Out[4]= 2 x 2 x 2 In[5]:= HoldForm[2*1*3] Out[5]= 2 x 3 In[6]:= HoldForm[1*2] Out[6]= 1 x 2 In[7]:= HoldForm[1*2*1] Out[7]= 1 x 2 x 1 Q.E.D. Indeed, the same happens with Hold and HoldComplete. I'd say this is a bug. Cheers -- Sjoerd On Feb 25, 11:07 am, "Q.E.D." <a...@netzero.net> wrote: > HoldForm[] is loosing the 1* when it...

Hi All, I have a column vector of numbers that I would like to extrapolate by "doubling up": e.g. turn 2 4 6 8 into: 2 2 4 4 6 6 8 8 any ideas on an easy vectorised way to do this?

Is there a simple way to get Maple to convert x^(3/2) + x^(5/2) to (x+x^2)*x^(1/2). I am willing to assume(x>0). Maple does recognize these as being equal: > p:=x^(3/2)+x^(5/2): > q:=(x+x^2)*sqrt(x): > simplify(p-q); 0 Here's a clumsy way to do it: > p:=x^(3/2)+x^(5/2): > assume(t>0): > subs(x=t^2,p); > simplify(%,{t^2=x}); > collect(%,t); Is there something simpler?

About upgrade 2.5 - 2.7 at $ 384.00 For most products I'm using - the updates (2.0 - 2.1 - 2.7) are free... 2.0 to 3.0 might be worth + 10-30% of the original price? VO is + full price again & again - Full program price for every minor upgrade/bug-fix? I dropped out of the money/bugs [VO] at 2.5 after starting at 1.0 more than 10 years ago. Certainly whoever is making VO have to make a living; earning moneys: - that is OK! A 10 years old VO site; - 10 years later, how much have changed? http://www.yi.com/prany/cavo/cavofront.htm Even MS is not ...

I tried all the betas and the RC (I'm using RC 1 now, but I'll try to upgrade to the final soon), and each one was prettier, faster, and had more features than the last.

Question How can i do that? I've been trying, solve, explot and subs. I can get the graph, but i cannot get the (x,y) pairs that I want. When I use function solve to solve the equation in term of x or y and then substitute the numeric value for one of them to find the other, I got the problem about complex numer. This might be because that numeric value that I substitute is not the number that satisfy the equation, so the program give me the result in complex number. Background. I need to use the pairs to find the optimal value of my objective function. I tried to use the fminco...

Hi I have 18 inputs (arrays) which contain certain statistics and if time = 3 seconds, set the values of time step 5.0 to -9999.0. I was wondering if there is an efficient way to do this without using a lot of case statements? Thank you. Hello AdrianT, it's not really clear to me what you want to do... I suspect: you have an array containing values and you want to output them with a fixed timing of 3 seconds: you should use a for loop autoindexing trough your array and sending the value to your indicator/output/whatever. Put a "wa...
