Images And Matlab

因為在下使用apple電腦，在XP系統下目前找不到print鍵....，所以只好用Matlab提供的存檔圖片，但是也因為檔案從fit變成jpg所以旁邊的功能也都會不見....只有中間那塊圖片...，po這張照片無非是跟大家都有照片好看一點而已，沒什麼意義....

Chapter 2 開始進入使用Matlab指令處理圖片

◈ 問題 :

① 當下Pixval on指令時，會出現Warning，why??

Warning: PIXVAL is obsolete.
IMPIXELINFO is its recommended replacement for pixel reporting.
IMDISTLINE is its recommended replacement for measuring distance.

In pixval at 73

figure2.3好像是要我們自行寫一個函數，然後執行那函數可以得到一些數值但我看不太懂他想表達的東西.
