Expressing Youself Using Code
我們有一個如下的cell資料
cdata = {'1'
'11'
'111'
'1111'
'11111'};現在要把他轉變成double型的陣列，很自然會想到的方法是cell2mat，可悲的是會遇到一個問題：
matlab要求每一行的資料長度要相同才行。
解決這個問題：
1、先把cell轉變成char陣列，在把他轉變成資料型別。原理是轉變成char之後的矩陣每行的長度是相同的。
str2num(char(cdata))2、使用cellfun函式，第一個引數傳遞對每個cell單元使用的函式名，第二個引數是cell名。
cellfun(@str2num, cdata)
