TFIND
searches for one or more strings (boolean AND) in a text file.
TFIND reports all lines where the string(s) were found (or NOT found
by option).
The search can be limited to a field in a fixed field (i.e. Column
oriented) list.
An extended search mode is available, where only letters and digits
are relevant.
Other options:
case sensitive search,
alternative errorlevel with number of hits,
header line with file name, LFN, custom prefix
A Windows FTP client written without CInternetSession or CFtpConnection classes. Demonstrates manual manipulation of Winsock sockets, FTP principles, and GUI concepts such as List controls with in-place label-editing and Column sorting, progress indicators, and reading and writing to the Registry
法國cromda編寫的新版本MATRICE 2(矩陣和矢量運算單元)。
// ----------------------------------------------------------
// 12-01-02 : MODIFIED Matrice to Matrice2 (Delphi 6)
// All routines now operate on rectangular matrix, except (InvMat and SysLin)
// No more need to use the InitMat procedure (suppressed) :
// - the routines detect automaticaly the dimensions of matrix and vector
// - error code MatDimNul is generated if zero lines or Column in matrix and vector (See DimensionMatrice and DimensionVecteur)
// - error code MatMauvDim is generated if the dimensions of matrix/vector don t allow valid result
// -
// The result matrix is dimensioned automaticaly
I built the Superlist control whilst developing an RSS reader called FeedGhost. Although there are plenty of commercial grouped list controls available I wanted to have total control over the code and of course its usability. Superlist supports drag drop Column customisation, grouping as well as handling thousands of entries smoothly. It s also highly customisable if you want to change its look and feel. In this article I ll explain how to use and extend the control in a demo project. If you download the source, you can find demo project under the Tests/SuperListTest directory.

Channel transmission simulator
Channel transmission simulator
%
% inputs:
% sig2 - noise variance
% Mt - number of Tx antennas
% Mr - number of Rx antennas
% x - vector of complex input symbols (for MIMO, this is a matrix, where each Column
% is the value of the antenna outputs at a single time instance)
% H - frequency selective channel - represented in block-Toeplitz form for MIMO transmission
% N - number of symbols transmitted in OFDM frame
%
% outputs:
% y - vector of channel outputs (matrix for MIMO again, just like x matrix)
% create noise vector sequence (each row is a different antenna, each Column is a
% different time index) note: noise is spatially and temporally white
* The keyboard is assumed to be a matrix having 4 rows by 6 Columns. However, this code works for any
* matrix arrangements up to an 8 x 8 matrix. By using from one to three of the Column inputs, the driver
* can support "SHIFT" keys. These keys are: SHIFT1, SHIFT2 and SHIFT3.
This software is a Matlab implementation of restricted sampling from Gaussian distribution, and sample x (Column vector) from N(x_mu, x_var), restricted in x_min<=x<=x_max.

Traveling Salesperson Problem
Our branch-and-strategy splits a branch and bound solution into two groups:
one group including a particular arc and the other excluding this arc.
1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound.
2.If a constant subtracted from any row
or any Column of the cost matrix, an
optimal solution does not change.
