1. 如何在matlab2014a中添加貝葉斯網路工具箱
你好
網路文庫圖文並茂教程地址：http://wenku..com/link?url=_qayAjfkqhQ3fpGZiNSp6-3W0FxKgkHDGgyZ0BI_-5tgD5Ap-mAVkVn0hXToSHW8VB963
你看看
2. matlab2014工具箱中有RAGA么
有的。
工具箱解壓到你的matlab程序目錄, 進入其中的子目錄gui, 在命令窗口運行:
>> flpath
就設置好了.
>>fraclab 啟動工具箱GUI界面
3. 盒維數和分形維數在哪一門學科中
圖形分形維數。這個可以在matlab中用Fractlab這個工具箱，這個工具箱可以在網上下載版。網上也有fraclab的使權用說明，打開界面後把圖導進去，選擇維數計算，然後選擇網格數之類的就可以了，我已經試過了。但感覺演算法有點粗糙。希望能幫到你。
另外還有一個方法，用ARCGIS軟體，我還沒有嘗試，只能算出一種維數，類似線路覆蓋維數。算維數一般有兩種方法，一種是網格法，一種是尺度變換法。前者針對方形圖形，後者主要是圓形。

5. 怎樣用matlab計算分形盒維數呢！
根據計盒維數原理求一維曲線分形維數的程序
function D=FractalDim(y,cellmax)
%求輸入一維信號的計盒分形維數
%y是一維信號
%cellmax:方格子的最大邊長,可以取2的偶數次冪次(1,2,4,8...),取大於數據長度的偶數 %D是y的計盒維數（一般情況下D>=1）,D=lim(log(N(e))/log(k/e)),
if cellmax<length(y)
error('cellmax must be larger than input signal!')
end
L=length(y);%輸入樣點的個數
y_min=min(y);
%移位操作，將y_min移到坐標0點
y_shift=y-y_min;
%重采樣，使總點數等於cellmax+1
x_ord=[0:L-1]./(L-1);
xx_ord=[0:cellmax]./(cellmax);
y_interp=interp1(x_ord,y_shift,xx_ord);
%按比例縮放y，使最大值為2^^c
ys_max=max(y_interp);
factory=cellmax/ys_max;
yy=abs(y_interp*factory);
t=log2(cellmax)+1;%疊代次數
for e=1:t
Ne=0;%累積覆蓋信號的格子的總數
cellsize=2^(e-1);%每次的格子大小
NumSeg(e)=cellmax/cellsize;%橫軸劃分成的段數
for j=1:NumSeg(e) %由橫軸第一個段起通過計算縱軸跨越的格子數累積N(e) begin=cellsize*(j-1)+1;%每一段的起始
tail=cellsize*j+1;
seg=[begin:tail];%段坐標
yy_max=max(yy(seg));
yy_min=min(yy(seg));
up=ceil(yy_max/cellsize);
down=floor(yy_min/cellsize);
Ns=up-down;% 本段曲線佔有的格子數
Ne=Ne+Ns;%累加每一段覆蓋曲線的格子數
MATLAB是美國MathWorks公司出品的商業數學軟體，用於演算法開發、數據可視化、數據分析以及數值計算的高級技術計算語言和互動式環境，主要包括MATLAB和Simulink兩大部分。
MATLAB是matrix&laboratory兩個詞的組合，意為矩陣工廠（矩陣實驗室）。是由美國mathworks公司發布的主要面對科學計算、可視化以及互動式程序設計的高科技計算環境。它將數值分析、矩陣計算、科學數據可視化以及非線性動態系統的建模和模擬等諸多強大功能集成在一個易於使用的視窗環境中，為科學研究、工程設計以及必須進行有效數值計算的眾多科學領域提供了一種全面的解決方案，並在很大程度上擺脫了傳統非互動式程序設計語言（如C、Fortran）的編輯模式，代表了當今國際科學計算軟體的先進水平。
MATLAB和Mathematica、Maple並稱為三大數學軟體。它在數學類科技應用軟體中在數值計算方面首屈一指。MATLAB可以進行矩陣運算、繪制函數和數據、實現演算法、創建用戶界面、連接其他編程語言的程序等，主要應用於工程計算、控制設計、信號處理與通訊、圖像處理、信號檢測、金融建模設計與分析等領域。
MATLAB的基本數據單位是矩陣，它的指令表達式與數學、工程中常用的形式十分相似，故用MATLAB來解算問題要比用C，FORTRAN等語言完成相同的事情簡捷得多，並且MATLAB也吸收了像Maple等軟體的優點，使MATLAB成為一個強大的數學軟體。在新的版本中也加入了對C，FORTRAN，C++，JAVA的支持。
