Code Definition and 908 Threads

I have least squares code which I am trying to rewrite in FORTRAN90. I have a pair of allocatable arrays declared in MAIN. I pass those unallocated arrays to a subroutine where the arrays are allocated and data is assigned. However, I get segmentation faults every time I try to run this...

I found some open source code in wx that I'm considering re-writing in qt and adding some new functionality to. It's for science research. Before I do, I wanted some feedback from the community if this is a worth while endeavor and an estimate of how long it would take. It's about 700 lines...

Homework Statement Hardware redundancy is important in many real-world engineering systems. Specifically, installing multiple sensors that measure the same quantity provides a level of safety in the event that one instrument fails during the mission lifetime. You do not want an expensive...

Hello, I am taking MATLAB this summer and will be having a number of questions on this forum about all my bugged code when I make it. Before I begin, I was wondering how do people add those ''code boxes'' when they make a thread that shows all their code within the post. Thanks Example: Post...

hello,every body ,I want to know is there any any free burnup code? thank you

I've been programming on and off for a few years just recently taking it seriously. Something I've always wondering about is how the computer understands the commands I type in. Is it essentially binary? and if so how could 1's and 0's possibly create something as complex as a video game or an...

Hi, all there is an example for gui but I can not do. Could somebody help me. I generated a button in gui then I have to add some function on in. Codes are in the picture. Will I add them under callback function? Why can I not determine where I should I add them. To understand it what...

hey guys, So I'm working on a MATLAB function that uses simpsons 1/3 rule to find an integral. This is what I have done so far, but I'm not 100% confident.. I seem to get double when I use greater segments. If anyone would be able to have a look at give me some tips that would be very much...

I have some F77 code and I am wondering if it is possible to inject external code into a separate file and call it without it being a subroutine, and placed into the code. An example would be : a = 1 + 1 b = a + 1 c = b + a a = c + b d = 4 + a and I want to take lines 3 and 4 and...

Hello all, Does it occur that anyone here working on OFDM communication systems? I need a MATLAB implementation of such systems in the continuous time. I will provide the math derivations if requested. Thanks

And this is why I'm going to hazard to guess that the next century of biology will be heavily dominated by the study of post translational modifications. The genome only encodes ~26,000 genes, and the entire end product of the genome+epigenetics--the proteome--only is comprised of roughly...

What is the capital equivalence of \ell (##\ell##) Also where can I find a list of such commands?

What is the most commonly used programming language for microcontrollers? I have done programming in machine code and it is a pain. I will get better at it if I have to, but would rather use a high level language like C. I hear C is much easier to write programs with than machine code...

Homework Statement Binary-to-Gray code converter,isn't it a decoder? The Attempt at a Solution

Hello everyone. Sorry if the question is silly, but in really need to know something. We know that The Fourier transform of time is frequency and the inverse of frequency is time. In Matlab can anyone tell me how to write it ? Because in the book Non linear fiber optics by Agrawal we found that...
