 MatLab心得和筆記  

日期:2021/10/08 

一.Matlab心得 

 

MatLab真的很方便， 

 

先以畫圖部分來說，我不會用C/C++繪圖，我稍微用Python繪圖但在繪圖前要先下載某些package，MatLab不需要下載任何額外的Package。 

 

第二，以環境設置來說，沒想到MatLab有"我的最愛"功能，我今天才知道，在我用的所有App中，第幾個有"我的最愛的"功能，在我用的所有程式開發環境(IDE)中，第一個有。 

 

第三，以功能來說，除了Script之外還有 LiveScript，當我寫完程式碼要執行時，他會將答案顯示在旁邊，而且可以存成檔案。除了Python外，我沒聽過有這樣功能的IDE。 

 

 

二.Matlab筆記 

 

1.Matlab應用 

太多了... 

(1)數學運算 

(2)信號處理 

(3)影像處理 

... 

  

  

2.符號 

(1)UpArrow: 命令尋找，往上找 

(2)DownArrow:命令尋找，往下找  

(3)%: 行註解 

  

3.矩陣 

 

(1)特殊矩陣 

company 

diag 

hankel 

 

(2)公用矩陣 

zeros 零矩陣 (所有元素為0) 

ones   一矩陣 (所有元素為1) 

rand   亂數矩陣 

rands 

eye 單位矩陣 (I) 

linspace 

logspace 

meshgrid 

 

(3)管理 

rot90 

fliplr 

diag 

tril 

triu 

 

(4)迴圈 

for  

while 

 

4.Preference 

Preference可以改。 
 

5.檔名 

支援文字和數字，不支援符號。 

 

6.功能介紹: 

 

太多了不知道要怎麼寫，QQ。 

1.有Script和Live Script 

Live Script是一個Script ，當我寫完程式碼要執行時，他會在旁邊顯示結果而且可以把它存成檔案，真的很方便。 

 

2.

diagonal matrix--diag

 diagonal matrix--diag how to create a diagonal matrix? diag() func. how to get  diagonal elements from a matrix? diag() func. [syntax][descr] (1) M=diag(Vector V,int k=0) will return a |V|*|V| diagonal matrix |V| is length of V When k=0, M is  |V|*|V| size, M[i,i]=v[i] , M[i,j]=0 , for 1<=i , j <=|V|  i!=j , where i and j is positive integer.  i.e.  value of  elements in M which its index belongs diagonal is equal to value of elements in Vector V, otherwise is equal to 0. translation:對角線索引的值為V的元素的值，非對角線索引的值為0 When k>0,  M is |V+k|*|V+k| size, M[i+k,i+k]=v[i] ,M[i,j]=0 for 1<=i , j <=|V|  i!=j , where i , j and k is positive integer.  [extra tips] You can think about M=diag(V), then add a row and column at left and button which all element are equal to 0. translation:你可以想M=diag(V)，然後把所有為0的元素加到最左行(第一行)和最下列(最後一列) When k<0,  M is |V+k|*|V+k| size, M[i,i]=v[i] ,M[i,j]=0 for 1<=i , j <=|V|  i!=j , where i and...
