Is the best way to go from research paper from quant trading algo to C via Matlab and MuPAD ?

 

Is the best way to go from research paper from quant trading algo to C via Matlab and MuPAD ?

This appears to be an interesting research development. I was playing with the following functions as displayed:

I just played with this in the Matlab command console:

>> syms x y t
>> z = (x^3 – tan(y))/(x^3 + tan(y));
w = z/(1 + t^2);
F = [w, (1 + t^2)*x/y; (1 + t^2)*x/y,3*z – 1];
>> matlabFunction(F,’file’,’testMatrix.m’,’vars’,[x y t])

ans =

@testMatrix

>> ccode(F)

ans =

F[0][0] = -(tan(y)-x*x*x)/((tan(y)+x*x*x)*(t*t+1.0));
F[0][1] = (x*(t*t+1.0))/y;
F[1][0] = (x*(t*t+1.0))/y;
F[1][1] = (tan(y)*-3.0+(x*x*x)*3.0)/(tan(y)+x*x*x)-1.0;

>> latex(F)

ans =

\left(\begin{array}{cc} -\frac{\tan\!\left(y\right) – x^3}{\left(x^3 + \tan\!\left(y\right)\right)\, \left(t^2 + 1\right)} & \frac{x\, \left(t^2 + 1\right)}{y}\\ \frac{x\, \left(t^2 + 1\right)}{y} & – \frac{3\, \left(\tan\!\left(y\right) – x^3\right)}{x^3 + \tan\!\left(y\right)} – 1 \end{array}\right)

>> pretty(F)

Is BlueGo the best way to install Boost for newbie C++ developers?

 

Is BlueGo the best way to install Boost for newbie C++ developers?

This is available here:

http://vertexwahn.de/bluego.html

This comments was posted here:

 I tried using BlueGo to install Boost. However, I failed. Although BlueGo does automate some things, it simply lacks the necessary documentation and explanations of ‘what to do next’. Of course, as a beginner who does not have much experience with things like Boost, I am very dependant on documentation and explanations to figure out what to do. While BlueGo may work for experienced developers, it is certainly a terrible option for beginners like me.

Matlab socket programming best way to trigger events with real time data provider like IQFeed

Matlab socket programming best way to trigger events with real time data provider like IQFeed

I may finally getting closer to figuring out how to stream data into Matlab using sockets. From within Matlab, it will directly connect into the IQFeed client. Outside of what you would think is difficult event handling with listeners, the coding looks stupidly easier but communicating with .NET assemblies or Java JARs is more complicated.Using Sockets within Matlab is much easier to just use a filter on the stream to listen to. If something triggers, you would issue a listener. Once I figure it out, this HFT may become born.

Is the best way to parallelize ARIMA in R using the quantstrat and backtest R packages?

I wondered about this post.

I really don’t want to hack the R packages to parallelize from within those.

If you got a better suggestion, please let me know by commenting.

Is this the best way to integrate R to Excel ? RExcel package?

Is this the best way to integrate R to Excel ? RExcel package?

 

=

In case you wish to read (write) excel spreadsheets into (from) R, you can use the ‘xlsReadWrite’ package.

For further applications and information, you are kindly asked to check the following reference:

http://www.londonr.org/May’10%20Markus%20Gesmann.pdf

There is this : http://en.wikipedia.org/wiki/RExcel

Would you like to import Excel data to R, or from R data to Excel?If you’d like to import Excel to R, you can use the several ways.

http://d.hatena.ne.jp/myopomme/20111208/1323350478 (Sorry, this is Japanese site)

If you’d like to export R data to Excel, Excel can automatically transform the tab separated format to Excel spreadsheet.
So, all you have to do is this code.

write.table(x, file=”hoge.xls”, sep=”t”, …)
* x should be data.frame or matrix.

On the other hand, you’d like to do both. I recommend to use the xlsx package. This package supports the Excel 2007 and old Excel format and very convenient.

http://cran.r-project.org/web/packages/xlsx/index.htmlhttp://d.hatena.ne.jp/myopomme/20110409/1302313511 (Sorry, this is Japanese site)

You need to be clearer. Are you looking to:

a) Write data out from R into Excel. And/or read Excel data into R for processing. (In which case Majeed Simaan and Akira Myomoto’s suggestions are spot-on)

or

b) Embed R routines within an Excel environment so that the user works in Excel but can get R to programmatically do something in the background return results to Excel, with the user unaware of your actions.

If it’s the latter, then RExcel is the way to go.
Before you ask, I’ve no experience with RExcel!

 

==

RExcel is pretty good but is only availble for free on a non comercial license. I’ve recently played around with R.Net, http://rdotnet.codeplex.com/ to write a simple Excel to R link in C# to avoid any licensing issues, http://sharpstatistics.co.uk/csharp/using-r-net-in-an-excel-add-in/.

If you want to have read/ write access- Please use package Rcmdr. Which is flexible.
