【正文】 I 摘 要 MATLAB 作為世界頂尖的數(shù)學應(yīng)用軟件,以其強大的工程計算、算法研究、工程繪圖、應(yīng)用程序開發(fā)、數(shù)據(jù)分析和動態(tài)仿真等功能,在很多領(lǐng)域發(fā)揮著越來越重要的作用。本論文主要研究基于 MATLAB 的概率統(tǒng)計可視化實驗系統(tǒng)的設(shè)計與實現(xiàn)。 本 系統(tǒng)的設(shè)計主要實現(xiàn)常見分布函數(shù)圖像的可視化。本文利用 MATLAB 軟件 ,結(jié)合概率論的學習體會,設(shè)計出概率論知識體系中常見的分布圖像 繪制 的系統(tǒng)??梢暬O(shè)計是本系統(tǒng)設(shè)計的重點,本系統(tǒng)的實現(xiàn)的基本繪圖功能有: 常見離散分布(超幾何分布、二項分布、泊松分布)的分布列圖的繪制; 常見連續(xù)分布 (正態(tài)分布、均勻分布、指數(shù)分布)的密度函數(shù)圖,分布函數(shù)圖的繪制。 通過基于 MATLAB 的概率統(tǒng)計可視化實驗系統(tǒng)的設(shè)計與實現(xiàn),本論文在促進教育思想觀念的轉(zhuǎn)變和促進學生創(chuàng)新能力和實踐能力的培養(yǎng)等方面將起到積極的作用;另一方面;數(shù)學實驗系統(tǒng)將促進教學手段的現(xiàn)代化和學生掌握先進的數(shù)學工具的步伐。 關(guān)鍵詞:數(shù)學實驗;概率論;圖形界面; GUI II Abstract As the best application software in mathematics, MATLAB has being more and more important in many areas due to its powerful function such as engineering calculation, algorithm research, engineering drawing, application development, analysis of date and dynamic simulation. This paper is focus on the design and application of visual experiment system on the foundation of the probability and statistic of MATLAB. The main design of this system is the visibility of mon distribution function. In this paper, the author used MATLAB to design the system of distribution drawing which is usual appeared in the knowledge hierarchy of probability theory. The design of visible system is the emphasis of this system, The system can realize many functions include the drawing of the scatter gram in mon discrete distribution (hyper geometric distribution, binomial distribution and exponential distribution), the drawing of density function diagram and distribution function of the figure in mon continuous distribution( normal distribution, uniform distribution, exponential distribution). According to the design and application of this visible system, this paper would have a positive effect on the transform of educational ideology. It also has a great promotion for students to foster their abilities of innovation and experiment. On the other side, the testing system of mathematics will also encourage the modernizing of teaching way and the using of advanced mathematical tools.
