The zlibex.pas unit included in this archive will work with delphi 5, 6,and 7. if you previously downloaded my delphi 5 unit, you will notice that the unit has been renamed. this was done because borland included in its delphi 6 and 7 lib directories a zlib.dcu file and i felt it was more correct to rename my unit and force developers to have to update their code than to make developers worry about the possible file contention in delphi 6 and 7.

這個無限位計算器，N!及N的平方了。本來是打算用堆棧去實(shí)現(xiàn)的，突然發(fā)現(xiàn)了BigDecimal這個好東東～～于是乎～～堆棧在偶的計算器里退休了。。。 這個是在JDK 5.0 update 3下用 NetBeans 4.1寫的，我試過了兩個1.4.2版本的，總說找不到MAIN()方法，對NetBeans打的包。。偶有置疑。。。所以拆開來。。。*.calss + 一個批處理＋*.java打成了個壓縮包傳了上來～～

The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become available. The module contains a test for singularities which is simpler and quicker than calculating the singular-value decomposition. An important feature of the algorithm is that it does not square the condition number. The matrix X X is not formed. Hence it is suitable for ill- conditioned problems, such as fitting polynomials. By taking advantage of the MODULE facility, it has been possible to remove many of the arguments to routines. Apart from the new function VARPRD, and a back-substitution routine BKSUB2 which it calls, the routines behave as in AS 274.

ACKAGE INSTALL =============== NOTE: if you get an error when installing TVideoGrabber on the component palette, probably that you need to apply a Delphi update pack (see details in the "update PACKS" chapter below).
