analysis

I want to generate Full and Partially Call Trees from cscope database of c and c++ projects in Linux. The project is rather large, so it can be not easy to work with the full call tree of project, so I want to limit call tree generation with grep-like filter of function names. And also I want to be able to build "called by" and "called from" sub-trees from any point. So tool must be interactive and easy to patch. PS: I want use cscope database, because it is already used in project and generating of it is rather fast. I use vim editor and have X windows system. There is cbrowser program on

I'm currently reading about algorithmic analysis and I read that a certain algorithm (weighted quick union with path compression) is of order N + M lg * N. Apparently though this is linear because lg * N is a constant in this universe. What mathematical operation is being referred to here. I am unfamiliar with the notation lg * N. The answers given here so far are wrong. lg* n (read "log star") is the iterated logarithm. It is defined as recursively as 0 if n <= 1 lg* n = 1 + lg*(lg n) if n > 1 Another way to think of it is the number of times that you have to iterate logarithm before the

I'm considering Prestashop for a new project. It seems to be younger than Zen-Cart and osCommerce. Since I just found it by Google, I'd like to gather comments and experience and comparison of Prestashop to established "brands" like Zen-Cart and osCommerce As one that love working with Magento i just wanted to show you this article. If i were in the works of setting up an site for online commerce, i wouldn't choose ZenCart or OSC. They are both old and doesnt update at all. But thats just an personal opinion. And i work a lot with these things. My Prestashop knowledge is limited though, but if

Q1. In my university studies of object-oriented modelling and design they recommend thinking about what an object can do for its method, and what its responsibilities are for its attributes. All attempts at clarification have resulted in further confusion. This tends to generate a class diagram with actors who have all the actions, and inner classes which only hold data. This doesn't seem correct. Is there another way of thinking about how to model the objects? Q2. Also, the course seems to emphasize modelling the objects after their real-world counterparts but it doesn't necessarily make

I've been thinking about this homework question for a bit now. Given an number array of size n, design an algorithm that will find the high and and low values with at most 1.5n comparisons. My first try was int high=0 int low= Number.MaxValue //problem statement is unclear on what type of number to use Number numList[0 . . n] //number array, assuming unsorted for (i=0, i < n, i++) { if (numList[i] > high) high = numList[i] else if (numList[i] < low) low = numList[i] } My problem is each iteration of the loop has one of three possibilities: low value is found - 1 comparison made high value is

I would like to know how I would go about performing image analysis in R. My goal is to convert images into matrices (pixel-wise information), extract/quantify color, estimate the presence of shapes and compare images based on such metrics/patterns. I am aware of relevant packages available in Python (suggestions relevant to Python are also welcome), but I am looking to accomplish these tasks in R. Thank you for your feedback. -Harsh Also check out the RASTER package on the R-Forge website: http://r-forge.r-project.org/projects/raster/ It is not released to CRAN yet but it is an excellent
