推 hugebird:我的作法是 用fgetl逐行讀到最後兩行 再取出你需要的數字 12/15 20:34
→ hugebird:記得讀完要把字串轉成數值 12/15 20:35
各位大大們好，小弟現在有一個txt檔如下
檔名:example.txt
內容:
max,min
PERFORM DRIFT TIME HISTORIES
Structure = Strcture 1
Analysis Series = PEER 2-1 IDA
Load Case =, [3] = [2] + PEER 2-1 Sa = 0.1g
Column 1 =, time (sec)
Column, 2, = drift no., 6, name =, 1st
Column, 3, = drift no., 7, name =, 2nd
Column, 4, = drift no., 8, name =, 3rd
Column, 5, = drift no., 9, name =, 4th
Maximum,0.0014368,0.0017769,0.0015642,0.0017663
Minimum,-0.001507,-0.001819,-0.0021522,-0.001507
我要的是最後兩行的數字然後轉成矩陣
0.0014368 0.0017769 0.0015642 0.0017663
-0.001507 -0.001819 -0.0021522 -0.001507
這樣的矩陣而已！不好意思有點趕，爬文了一些也看不太懂^^"
拜託了!!
