第二章

這禮拜開始講些有關指令的部份了
老實說因為是原文書我花了不少時間去看
雖然有老師還有同學的筆記
但是還是有些指令有點不太懂
但稍微操作過後不懂的情況就比較好了點
話說我在開檔的時候出了些問題
就是在圖片之前阿
會出現亂碼
而且還不是很短的那種
是很長很長的.....
害我完全不知所措....
後來還是無法......
不過其他的程序倒是很順利就是了
我想關於這個問題我得去找同學問了
以下是我的程式碼:

>> figure,imshow(s),pixval on

IMPIXELINFO is its recommended replacement for pixel reporting.
IMDISTLINE is its recommended replacement for measuring distance.

以上是我的程式碼
或許還有些細節我不是很懂
但我想再給我多一些時間
我會把它弄懂的
