This GUI can be used by entering nu at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function s integral can be evaluated over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.

為解決傳統可視倒車雷達視頻字符疊加器結構復雜,可靠性差,成本高昂等問題,在可視倒車雷達設計中采用視頻字符發生器芯片MAX7456。該芯片集成了所有用于產生用戶定義OSD,并將其插入視頻信號中所需的全部功能,僅需少量的外圍阻容元件即可正常工作。給出了以MAX7456為核心的可視倒車雷達的軟、硬件實現方案及設計實例。該方案具有電路結構簡單、價格低廉、符合人體視覺習慣的特點。經實際裝車測試,按該方案設計的可視倒車雷達視場清晰、提示字符醒目、工作可靠,可有效降低駕駛員倒車時的工作強度、減少倒車事故的發生。 Abstract: A new video and text generation chip,MAX7456,was used in the design of video parking sensor in order to simplify system structure,improve reliability and reduce cost. This chip included all the necessary functions to generate User-defined OSDs and to add them into the video signals. It could be put into work with addition of just a small number of resistances and capacitors. This paper provided software and hardware implementation solutions and design example based on the chip. The system had the characteristics of simplicity in circuit structure,lower cost,and comfort for the nature of human vision. Loading road test demonstrates high video and text display quality and reliable performance,which makes the driver easy to see backward and reduces chance of accidents.

zemax源碼: 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.
