Dear all, Iam looking for a generic code that could express the following functions: Subscript[mata, 1] = hl[[1]]; Subscript[mata, 2] = matg[[2]].hl[[1]] + hl[[2]]; Subscript[mata, 3] = matg[[3]].matg[[2]].hl[[1]] + matg[[3]].hl[[2]] + hl[[3]]; Subscript[mata, 4] =...

Homework Statement Suppose n\leq2 Let C be the code consisting of all binary strings of length n in which the sum of the bits is even. Is C and MDS code? is C a cyclic code? Homework Equations An MDS code is one where the codewords are separated by a maximum number of bits d. MDS codes obey...

I recently deleted my Latex code for my dissertation and now I'm starting from scratch. In my last code I had a line of code at the beginning that does all of my auto fitting for brackets, fractions etc. without having to worry about using \Bigg etc. but I can't seem to remember what it is, I...

I'm about to start a module in C++ programming and I was just wondering if the code I learn in college (on P.C's) will be useable on macs Xcode. As in will I be able to EXACTLY the same code on both?

http://www.bbc.co.uk/news/science-environment-14492948" Just want to discuss this development. IMO, we are not prepared for this kind of revolution, unless we fully understand the implications and effect of engineering the genetic code without exactly knowing the outcome. I know this is...

Hi all, I have written a paper which I wanted to put in arxiv classical physics section. I sent an endorsement request to an endorser in the relevant section and he agreed to endorse the paper in arxiv. He asked me to send him the 6 character alphanumeric endorsement code as suggested...

Hi all, I have discretized my equations in a way that for example the velocity depends on the velocity of the previous neighboring element so: h = number of elements t = 0: 0.5 : 10 for j= 1 : length(t) for i = 2: h v(i,j) = v(i-1,j) + b p(i,j) = p(i,j) +b end end This is not my...

Hi everyone I've been doing maths for quite a while now, but have never done any programming until recently. What I'm finding difficult is how you go from an initial value/boundary value problem on a bit of paper to a piece of code that will approximate the equation. I've done a bit of book...

having watched the film source code where they try and persuade that quantum physics allows for the brain to contain infinite parallel worlds i wondered if anyone made sense of it. As far as i could tell it was total rubbish from start to Finnish. Even down to the guy managing to send a text...

Sometimes when I try to debug my codes, VC++ brings me something I believe are assembly codes which I couldn't read at all. I want to know where I can learn these to better understand what is going on at low level. I am quite comfortable with high level programming, but I believe I really need...

Hey, I'm working on a DSP project that is using Matlab to improve the detection ratios of Computer aided Diagnosis (CAD). However the companies that are capable of doing this sort of CAD ensure that their code is not distributed. If anyone has or knows how to get a piece of code like...

Dear Programmers I am having text file having huge data. From the text file i would like to map the two numbers that are present in the same brackets and the values should not considered if they are present in different numbers. say for example I want to map number "4758 & 3895" that are in...

I had installed FileZilla FTP freeware on my computer. Later, I was unable to edit my HTML file (pushed wrong button?) Whenever I tried to open or edit it using Word (my only editor which now seems to accept HTML), the webpage would appear, rather than the text code. I am using Windows 7 on...

What good sources are there to learn latex code? Because I'm finding it frustrating trying to post up homework problems and trying to use paint with my laptop is equally frustrating.

I realize HTML isn't strictly a 'coding language' or so I've heard. I have a good friend who has a site he needs to prevent users from 'right clicking and copy'. Its a guitar tab site and he has spent relentless hours transcribing a band whos songs are far from easy. So to prevent, to a certain...

Not sure where to post this. I'm trying to write my dissertation, and both the examiners and I would prefer it if I used latex for the required notation. The frustrating thing is that even though I do know how to produce latex code, I don't know how to save it into a format that the computer...

Matlab R2011a's new feature: "portable C/C++ code directly from MATLAB" Does anyone have more information about it? Does this mean that we could write most of our C code using MATLAB first, and then run the MATLAB coder? (C is important for speed, but MATLAB makes displaying output and...

This may sound like a stupid question, but binary code seems so "simple", but it's been with us since the 1940's. What'd be wrong with tertiary code, say?

This is the code I have: #include <iostream> #include <cstring> using namespace std; template <class X> X mode(X *data, int size) { register int t, w; X md, oldmd; int count, oldcount; oldmd = 0; oldcount = 0; for(t=0; t<size; t++) { md = data[t]; count =...
