Wythoff's square array is Sloane's reference A035513 in the online encyclopedia of sequences (click the "table" button to see the sequence as a table) and Allan Wechsler's sequence is A022344. To my knowledge the following connection has not been noted before. Let T(i,j) be defined from the...

Hello I have a bunch of data in a text file that got loaded into an array. Now the problem is that there are a lot of outliers. So let's say if I find the outlier, how do I get rid of it, by say move the next one to that spot. If I do that how do I redefine the arrary size. What would be...

There's a lot of products with LED's these days. However I was wondering why a light made with LED's is done with an array on LEDs instead one large one. Can we not make a large one? Is it possible to make a large LED but it's actually more efficient to have several smaller ones? Any...

Hi, I realize this is a physics forum, but thought someone may be able to help! I would like to create a square array i.e 4x4 and then plot a vector of data (16 elements) over this 4x4 array. I have created the following code, it doesn't work but that's what I am ideally aiming after...

Hi all, I'm new to this forum and I'm not a physicist. I'm a Cabinet Maker looking for a career change. I performed an advanced search on the entire site and was surprised to find not a mention in regards to Halbach Array. My understanding is that the special arrangement of nib magnets can...

i need to get this array to calculate the numbers that are less than the average and greater than or equal to the average. first of all, i need to figure out how to make a counter to count the average of the array! i can't find the code in the textbook here's what i have so far: #include...

To those who helped yesterday,again, thanks. I have managed to resolve most of my problems, however, i have a new issue. VB seemsto think that the names of my arrays are "ambiguous", WHY? what do i need to do to resolve this new and fustrating problem?

see diagram for this at http://img.photobucket.com/albums/v11/biggm/cap.jpg Question: Determine the eqivalent capacitance C between terminals X and Y of the infinite set of capacitors represented. Each capacitor has capacitance Co. Suggestion: imagine that that ladder is but at the line...

int f[5]; Is it possible to do f[i]+=1; inside a valid for loop? If not than how can I increment integers stored in an arrary for each i in C? Thanks

consider the program Class A { int a; public: A(int m = 0) { a = m; } } int main() { int i = 0; /* Intansiate/Initilize Object with the Constructor */ A Object(0); /* Here is the Problem */ /* Create the 32 Objects of Class A */ A nObjects[32]...

The following array is based on the Fibonacci series. The first row is simply the Fibonacci series. Each nth row are Fibonacci type series where the generating numbers in columns 1 and 2 are determined as follows. The numbers in column 1 are the row number and the number to the right of the...

Antenna array consists of two infinite plane parallel sheets in the xy plane spaced half a wavelength apart and having current densities. Wave is propagating in vacuum. J_{s1} = J_{so}cos(\omega t) \vec{i} z = 0 J_{s2} = J_{so}sin(\omega t) \vec{i} z = \frac{\lambda}{2} The...

Hi some questions have been plaguing me when I look up at the sky. 1) Does anything exist between galaxies? Are there any lonely stars, black holes, rocks, planets,gas or anything between galaxies. Or do these things only form within galaxies? 2) I know about black holes, but I can't...

A[r,c] = \left(\begin{array}{cccccc} \frac{1}{2}\multsp \left(1+{\sqrt{5}}\right)&-&-&-&-&...\\ \frac{1}{4}\multsp \left(2+{\sqrt{8}}\right)&\frac{1}{4}\multsp \left(1+{\sqrt{5}}\right)&-&-&-&...\\ \frac{1}{6}\multsp \left(3+{\sqrt{13}}\right)&-&\frac{1}{6}\multsp...

I believe I am stuck. :frown: I need to traverse an array which will contain a sentence the user enters and identify the array positions of the first and last letters of each word in the sentence. I can do the first word, but I am not sure how to move it along after that. I am thinking I need...

How do you return the largest numeric value in an array, in Perl?

Array operations in Matlab? Is it possible to apply operations to the rows of a matrix as an array? Such as I have a matix A which is 30 rows by 1 column and I want to treat each row as a vector such that I can solve for the polynomial roots of each row using the roots comand (treating each row...

Does anyone know of a site that has some problem solving using FOR loops and or Arrays?

... | ... R ... | -R- --R ... | ... R Suppose you have an infite array (2by2) of resistors, each of value let's 1k. If you place the an ohmeter accres one resistor, what resistance will the ohmeter read?

I have a programming assignment to fill an array with this series: 1,4, 9, 25, 36, …. The problem is I don't know what this series is so I can't write the program. Can anyone help?

Hi, I hope you can help, I'm trying to create an array of characters in matlab: It has to be 100 x 5000 in size, I'm not to sure where to start. I've looked at some web resources and it some mention bringing in java strings? I'd ideally not like to use java as i want to learn the core...

Is limit of an array average of its terms?

My array is big. No, bigger than that. It's big! I'm writing a C++ program on a unix box (or is it linux? I never notice the difference), and I want to operate on a very large amount of data: more than 2^32 bytes. Do I have any options aside from writing my own code to manage a swap file...

Hello, I have a little function I have written that takes an array of structures as an argument void print_names(struct pers_info arr[]) { printf("Here is person 1: %d %s %s %s\n", arr[0].ssn, arr[0].pers_name.first,arr[0].pers_name.middle, arr[0].pers_name.last); printf("Here...

Could someone explain to me "array notation" I found it here, but I still don't understand it. Though I probably don't need to know it, I want to. Also, will I encounter this anywhere else? http://members.aol.com/hedrondude/array.html

I am not sure I wrote this correctly, but I am trying to declare an array of 12 pointers to arrays of 50 characters: char *names[12] [50] Does this look OK? Thanks.

I'm not sure that this post belongs here, but I'll give it a try. I'm having a devil of a time :devil: trying to figure out why my program won't work. The assignment was to create and array class consisting of: A constructor that takes and integer for the size of the array A constructor...

Why do we use two channels in MICRO ARRAY analysis ?? LIke red and Green ?? What does the ratio between red/green signify ??

I moved into a new condo last week. It has concrete block walls and concrete floors and ceilings. Needless to say, the wireless reception is terrible. I bought two of http://www.hawkingtech.com/prodSpec.php?ProdID=183 - 90 degree directional antennas. They helped a little, but...

Just wondering if anyone happens to have an electromagnetic diagram of how a four antenna array would look. Provided that all four antennas’ form a square and edges are one wavelength in distance? Thanks Philip

OK here is what I am trying to figure out there is a large factory by my house which towers about 4 stories above the surrounding community. on the roof there is an array of 802.11b anttenas (im assuming its B and not A cause B has larger range) there are 10 large anttenas, 5 on one side of...
