Hi, Matlab noob here. I need your help to simplify this Matlab source code. Here the code that i currently use for k=1:1:gg k1=gains(k,1); k2=gains(k,2); k3=gains(k,3); . . kn=pidgains(k,n) [T,X,Y]=sim('Evaporator_PID',[Tstart Tfinal],opt); end...

The following question pertains to programming, but I have posted it here because I want the views of mathematicians (also of physicists and engineers), not those of computer scientists (which i already know) and I do not know how many of the former category care to look into programming...

Hi all, (1.) Can someone tell me the difference between a compact valued and single valued correspondence? (2.) I have been seeing repeating themes of "continuity on a compact set". Does that imply boundedness and thus possible to attain maximum? (3.) What's the difference between...

Howdy All! I have been lurking in the shadows of physicsforums for a few months now, but this is my first official post here. A bit of background about me. I'm technically in my second year of university, but I say "technically" because I more or less squandered away my first year. I'm...

University has finished for me this year until late February of next year, so i currently have plenty of spare time (and loving it) :smile: Normally over the summer holidays i like to just have a break from uni study, but i am still always keen to learn something--something that i want to learn...

The question is What will be the output? #include<stdio.h> int main(void) {float y=6/4; printf("%.1f\n",y);} The answer is 1.0 I got that right by trusting my senses:biggrin:; but I want to understand why.

So I am taking an intro to programming class and am doing pretty well. I am getting high 90s on all assignments and end up helping others during lab time (used to practice programming). However, on our last exam I got a B on the test (about average). Not too bad, but I know I can do better. Now...

I am in a class where we are studying concepts and design of programming languages. For a project we are suppose to design our own programming language or come up with some alternative project idea to do for the class. So, my question is... do ya'll have any ideas for an interesting and...

I was wondering whether anyone has experience in astronomy simulations. If so, what language do you use and recommend? I've done Haskell and a very small bit of C++... I've been told Python is good, what are your thoughts? Also are there any good websites that may get me started? Thanks

I'm currently in a computer science class in my senior year of high school and we're learning java. I was wondering if this is going to be the language I would be using in the workforce after college if I graduate with an interactive media degree. I've heard multiple people say that java is a...

Hi! I'd like to do a PhD in theoretical particle physics, but I have the following problem. I found an advertisement, where I should work on numerical algorithms for the calculation of some certain integrals. Furthermore, I should work on Monte Carlo simulations. During my master thesis...

with which programming language is v-bulletin (on which pf runs) made? Was it created by you Greg? How much time did it take to build it?

Ok, so apart from my desire to become a Physicist or Engineer I've also considered going into a more computer related career in either networking or programming. Yea, let's face it I haven't really been able to decide. One way or the other I'd like to be prepared or at least know what I'm...

Hello all, I am new to programming and fortran, I have Intel Fortran 9.1 and using this via Microsoft Visual Studio 2005. To start with I have found a simple exmaple from the a Intel Fortran 90 book. I seem to be able to run a debug, but can't seem to create an executable? Its my first time...

Hello, I just started taking a computer science course involving the program language c. I was wondering if anyone know the command that enables the user to type in a numerical input into the program. For example: 1. The user runs the program "Math Wizard." 2. The program displays...

In my computer science class my prof rambled off into examples, one of which was atoms. He said that atoms were just a model for something that we really can't understand yet. Is this correct or is he under some kind of influence or a complete idiot (likely, he teaches programming 'backwards').

Object: Write a program that read digits and composes them into integers. For example, when you read 123( in characters) the program should print: "123(in integers) is 1 hundred and 2 tens and 3 ones". My first attempt is first read the number as a string then convert its characters to...

I've been looking for a free download of a programming language that is easy to use and handles large numbers for a number theory problem I'm working on. I will report my results here after I use it. My TI isn't powerful enough and my other programmable calculator that I downloaded, graphcalc...

Writing a function problem If m different species share the same habitat the model becomes a system of recurrent equations: Ni+1 [1] = Ni [1] + r [1] Ni [1] ( 1 - Ni [1] / K [1] ), Ni+1 [2] = Ni [2] + r [2] Ni [2] ( 1 - Ni [2] / K [2] ), ……………………………………………………, i = 0, 1, …, i , i + 1, … (2)...

Hello, Lately I've been trying to gain an understanding of processors/cpu's and the very lowest possible code you can engineer. I decided I would do a thought experiment where I would distill the computer down to the most basic level I could conceive, and decided that such a computer would...

Electric Engineering Curriculum no programming class? http://www2.eng.usf.edu/studentServices/docs/guides/Curriculum20092010.pdf So if you open that pdf and go to page 8 "Bachelor of Science in Electrical Engineering" i don't need to take any programming class? how come??

I understand that you can write a complete operating system in a high-level language like C++, compile it into machine code, and then write it to storage, and then sell it or give it away. But is this historically what was done? Did the compiler come first, or the operating system? When you...

It is suggested that I learn a computation oriented programming language for an physics internship which I hope to apply for soon. I'm curious; what is the most commonly used programming language in the physics community? I've heard that Fortran has been used extensively for a some time, but...

Hi, Any good primers for programming some simple programs on the HP35s? I have some inputs but am unsure how to do so exactly. Also if a good quadratic formula editor in algebraic mode is available that would be nice too. thanks, Whalstib

I was reading that while you study a Bsc in Theoretical Physics, you learn how to do quite a lot of programming. I am quite unfamiliar with programming but I was wondering how transferable are the programming skills you learn? Are they applicable to things like web design etc? Or are they only...
