It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the series. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the series? Series Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2....
I need to dynamically add series to an MSCHART ChartArea. I retrieve column names from a datatable. The series name needs to be the column name. I can build the SERIES ADD in a string, but then what? Series Trigger_Level = chart1.Series.Add("Trigger Level"); Developing in C# Please advise Bill ...
Hi, I use Flex ColumnChart and set ColumnSeries in ColumnSet with dataFunction. The function I need is to change series by user interaction, so I add a button to pop series from myChart.series (actually I get a array = myChart.series, pop the series, and assign myChart.series = array). However, when I click this button, the last series...
I have an application which will store a series of (float) values in an XML file. There could be upwards of 100,000 values so I am interested in keeping the size down, but I also want files to be readily accessible by third parties. There seem to be various methods open to me as far as encoding the data within the XML: 1. <data> ...
I think this is a pretty common issue, but I don't know what the process is called, so I'll describe it with an example. The concept is that I want to join a sparse dataset to a complete series, such as the days of the week, months of the year, or any ordered set (for example, for ranking). Empty positions in the sparse data will show as...
I need to create a custom series class for the Silverlight 4 toolkit (April 2010 drop). There is a tutorial here: http://themechanicalbride.blogspot.com/2009/03/writing-your-own-silverlight-chart_25.html that references an older version of the framework. There have been enough changes that this doesn't work. Can anyone point me to sam...
Hello, I'm looking for a line of code that identifies missing files in a series of files and exports that list to a txt file. For example: a directory called 1to100000 contains pdfs named 1,2...99999,100000 but is missing some from the series. I would like the script to report those missing files to a txt file. Ideally this would be an ...
Hello everybody, I'm seeking advice for a problem that I thought to be simple, and it might be simple indeed by creating a small script, but I think there should already be a way to do that with git/quilt/stgit. I'm not exactly good at git and this is causing some issues to me. My problem: I've got a git tree (linux kernel) and a numbe...
Hi, I am wondering how can I do clustering of time series data. I understand if the data is a point. But I do not know how to cluster if the data is time series with 1XM where M is the data length. Especially the part on how to compute new mean of the cluster for time series data. My X matrix will be N X M where N is number of time ser...
Hello I have a zoo time series with missing days. In order to fill it and have a continuous series I do... I generate a chron date-time sequence from start to end. I merge my series with this one. I use na.locf to substitute NAs with las obsservation. I remove the syntetic chron sequence. Can I do same easier? Maybe with some index...
I've got a sample size of 180 data points. Its somewhat of a noisy sine wave. Trying to figure out the period / frequency of the data . Working in Xcode - read over the Accelerate framework but it seems very complex. Any suggestions on how to get the period / frequency of the data ? ...
Does anyone know how to or found any good examples of explicitly setting the color of the data points series when using the WPFToolkit chart control? I would like to set this as a style in my XAML. ...
Is there any formula for this series? I think it is a harmonic number in a form of sum(1/k) for k = 1 to n ...
Hi All, My problem is I have an array of objects of size N. after every time (t+1), some of the values of the array may or may not change. so lets say t+1 index 15 changes but everything else stays the same. What is the most efficient way to store something like this (in memory ) apart from just having an array of arrays of course? I w...
I use Excel 2007. I have 10 items: Col1, Col2 One, 1 Two, 7 Three, 45 Four, 2 etc When I make a bar chart the series is one colour, so each bar in the chart is the same colour. I would liek each bar in the chart to have a different colour, gradient or random.. I can do it bu switching the labels to be at the side, but i would like...
Hi All I just have a quick question, on how to speed up calculations of infinite series. This is just one of the examples: arctan(x) = x - x^3/3 + x^5/5 - x^7/7 + .... Lets say you have some library which allow you to work with big numbers, then first obvious solution would be to start adding/subtracting each element of the sequence u...

Hi all, I've an variable as page number (page) whose values increment by one each time. [Page numbering] But, now I need to customize this numbering to 1,1,2,2,3,3.. Can you suggest any formula for generate this kind of series? EDIT: (Answer) After playing with macros and VBA for some time I've figured out a way to generate this type...
