New users and old of optimization in MATLAB will find useful tips and tricks in this document, as well as examples one can use as templates for their own problems.
Use this tool by editing the file optimtips.m, then execute blocks of code in cell mode from the editor, or best, publish the file to HTML. Copy and paste also works of course.
Some readers may find this tool valuable if only for the function pleas - a partitioned least squares solver based on lsqnonlin.
This is a work in progress, as I fully expect to add new topics as I thInk of them or as suggestions are made. Suggestions for topics I ve missed are welcome, as are corrections of my probable numerous errors. The topics currently covered are listed below
Just what is a regular expression, anyway?
Take the tutorial to get the long answer. The short answer is that a regular expression
is a compact way of describing complex patterns in texts. You can use them to search
for patterns and, once found, to modify the patterns in complex ways. You can also use
them to launch programmatic actions that depend on patterns.
A tongue-in-cheek comment by programmers is worth thInking about: "Sometimes you
have a programming problem and it seems like the best solution is to use regular
expressions now you have two problems." Regular expressions are amazingly
powerful and deeply expressive. That is the very reason writing them is just as
error-prone as writing any other complex programming code. It is always better to
solve a genuinely simple problem in a simple way when you go beyond simple, thInk
about regular expressions.
Tutorial: Using regular expressions
SD card controller can just read data using 1 bit SD mode.
I have written this core for NIOS2 CPU, Cyclone, but I thInk it can works
with other FPGA or CPLD. Better case for this core is SD clock = 20 MHz and
CPU clock = 100 MHz (or in the ratio 1:5). If you have a wish you can achieve this core.
Good luck
Lotus Notes開發(fā)用的在線DHTML編輯器,基于Active X control
1. This rich text editor is based on the editor used in an older sandbox posting I found. The majority of this code was NOT written by me. Credit goes to someone at Lotus (I thInk) for the original code. I only extended the base
code to add more features, such as cut/copy/paste and adding tables.
2. This editor is based on an Active X control, so it will only work in Internet Explorer. I tested this in IE 5.5, but I thInk it should would in IE 5.x The Active X control is marked "safe for scripting" and should not trigger a warning from your browser about unsafe content.
This text introduces the spirit and theory of hacking as well as the science behind it all it also provides some core techniques and tricks of hacking so you can thInk like a hacker, write your own hacks or thwart potential system attacks.

Make a Driver is difficult, it need some experients.
When you write it, you will be fault to other fault. i thInk that, this book is good to make driver use WDM(window driver model)
