基于STM32的手写识别，使用STM32战舰V3开发板，STM32F3ZET6。在LCD触摸屏幕中，滑动手指，可以识别手写的字符和数字。(STM32-based handwriting recognition, the use of STM32 warship V3 development board, STM32F3ZET6. In the LCD touch screen, slide your finger to recognize handwritten characters and numbers.)

使用matlab对卡尔曼滤波算法模拟，结果精确可用(Use matlab on the Kalman filter algorithm simulation results available)

VC++ 开发虽然已经很很多年了，但是还是有很多经典的例子可以拿来好好的分析 学习下。其中涉及到的功能非常值得在其他类似的项目中借鉴。互相学习中

zemax源码： This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.
