I would like to plot for any function this grid : This is the special case for f(z) -> 1/z This is a typical graph you can find on wolfram alpha. Nevertheless I don't know how to proceed. The idea would be to see where the lines of the complex grid of the 1-square is sent after applying f. One thing that could be great would be to add colors on the grid in order to see where the left part is sent. (like here : https://www.youtube.com/watch?v=JX3VmDgiFnY ) If you have any idea... thank you. Try the code below. I have updated the answer to show the lines in different colors. clear clc N = 101; x

I know that I asked the same question before, but as I am pretty new here the question was asked poorly and not reproducible. Therefore I try to do it better here. (If I only edit the old one probably nobody will read it) I have this double integral that I would like to integrate: Here is a picture ff<-function(g,t) exp((16)*g)*exp(-8*t-(-t-0.01458757)^2/(0.0001126501)) integrate(Vectorize(function(t) integrate(function(g) ff(g,t), -2.5,0)$value), -2, 2) Running this in R gives me the error: the integral is probably divergent When I try to run the sam function in Wolfram it gives me a proper

I'm using the Wolfram Alpha API wrapper for .NET at this location http://products.wolframalpha.com/api/libraries.html However it's written in VB.NET and written for version 1.0 of the API. It's unusable. Does anyone know of a better API wrapper? Here is code that will work with the new API; I got it from Azure Dallas //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // <

I'm trying to normalize data and link records according to legal business entity name. Where can I determine the legal business name, and general information about that company? I will have at least one of the following: Stock symbol, DBA (short name), dns name, or full legal name. So far I've discovered that with the Relying on whois gives me private, or out of date information Wolfram Alpha API gives me most of what I need for public companies but nothing helpful for private companies like LEGO Parsing webpages for the (c) symbol may help in the resolution process, but doesn't match a name

My purpose is to find a eigenvectors of a matrix. In Matlab, there is a [V,D] = eig(M) to get the eigenvectors of matrix by using: [V,D] = eig(M) . Alternatively I used the website WolframAlpha to double check my results. We have a 10X10 matrix called M : 0.736538062307847 -0.638137874226607 -0.409041107160722 -0.221115060391256 -0.947102932298308 0.0307937582853794 1.23891356582639 1.23213871779652 0.763885436104244 -0.805948245321096 -1.00495215920171 -0.563583317483057 -0.250162608745252 0.0837145788064272 -0.201241986127792 -0.0351472158148094 -1.36303599752928 0.00983020375259212 -0
