问题 I am trying to understand the following Matlab definitions for RelTol and AbsTol parameters: RelTol — This tolerance is a measure of the error relative to the size of each solution component. Roughly, it controls the number of correct digits in all solution components, except those smaller than thresholds AbsTol(i).The default, 1e-3, corresponds to 0.1% accuracy. AbsTol — AbsTol(i) is a threshold below which the value of the ith solution component is unimportant. The absolute error tolerances

问题 Hi i am integrating twitter to android through twitter4j.I can successfully read tht tweets posted by me. Now i amtrying to posting tweet from it.but i cant. I am getting strange warning as below: 02-01 16:28:43.298: WARN/System.err(729): 401:Authentication credentials were missing or incorrect. 02-01 16:28:43.308: WARN/System.err(729): {"request":"\/1\/statuses\/update.json","error":"Read-only application cannot POST"} 02-01 16:28:43.308: WARN/System.err(729): TwitterException{exceptionCode=

问题 Actually I want to make an application which will getGlobalEvent and control that event through another custom application. Is there any way to do so. Can i get global event from a particular application? Its like an application which will lock custom application in your blackberry, if you add following application in that locking app list and put password to access then when u try to open that application, it will ask for a password which u set in the locking app. 回答1: Common advices this

问题 in a 'native' Zend Framework application I would enable the use of ezComponents by adding the autoloader of ezComponents to Zends autoloader: $autoLoader = Zend_Loader_Autoloader::getInstance(); require_once('../library/EZComponents/Base/src/base.php'); $autoLoader->pushAutoloader(array('ezcBase', 'autoload'), 'ezc'); Now, I'm wondering how I could do the same with Magento. Is there a way to extend Varien_Autoload (magentos autoloader) to enable easy integration of ezComponents? OR: Is there

问题 I have written a short monte carlo integration algorithm to calculate an integral in Fortran 90. I once compared the result obtained by solving the integral with respect to some parameter using the intrinsic random number generator with the random number generator method ran1 presented in Numerical Recipes for Fortran90 Volume 2. Running the same algorithm twice, once calling the intrinsic random_seed(), then always call random_number() and once calling the ran1() method provided in the

问题 I've tried to embed a .NET WinForms graph (Stephan Zimmermann's Graph Display) in a WPF window, under a WindowsFormsHost (I've referenced both System.Windows.Forms and WindowsFormsIntegration). However, I can see the form panel but not the graph. I've ran the demo application on a windows form and it worked, but when I transfered the same code to the WPF window, I saw that the data is updated but not shown on the graph. Thank everyone in advance, Yaron. 回答1: Could you try the following code

问题 Currently I have a WPF application in C#, but I'm finding it to be incredibly difficult to find any useful ways to embed a PowerPoint presentation into my window. One solution I found here: Embedding a Powerpoint show into a C# application This solution created the problem of having PowerPoint run in another window, but just display its UI within the WPF application. This meant that when the WPF window was focused, the PowerPoint presentation was not, and stopped playing. There was also the

问题 My optimization task deals with calculation of the following integral and finding the best values of xl and xu : Iterations take too long, so I decided to speed them up by calculating integral for all possible values xl and xu and then interpolate calculated values during optimization. I wrote the following function: def k_integrand(x, xl, xu): return((x**2)*mpmath.exp(x))/((xu - xl)*(mpmath.exp(x)-1)**2) @np.vectorize def K(xl, xu): y, err = integrate.quad(k_integrand, xl, xu, args = (xl, xu

问题 I have a x,y distribution of points for which I obtain the KDE through scipy.stats.gaussian_kde. This is my code and how the output looks (the x,y data can be obtained from here): import numpy as np from scipy import stats # Obtain data from file. data = np.loadtxt('data.dat', unpack=True) m1, m2 = data[0], data[1] xmin, xmax = min(m1), max(m1) ymin, ymax = min(m2), max(m2) # Perform a kernel density estimate (KDE) on the data x, y = np.mgrid[xmin:xmax:100j, ymin:ymax:100j] positions = np

问题 In RIM Blackberry OS 4.6+ there is a new feature - ability to show notification icon in statusbar. Integrated application use it to give quick and informative information for user: Dealler - missed calls, Messages - unread messages etc. removed dead ImageShack link Possible use of notification icon: missed events RSS updates object status (ex. weather/app activity/gps signal strength) other I would like to post a howto guide for this feature. 回答1: ApplicationIndicator class To add/modify
