matlab textscan headerlines 在 [問題] textscan及delimiter的用法? - 看板MATLAB - 批踢踢實業坊 的必吃
不好意思
目前遇到了一個難題，還請大家給點建議
現在手中有一個文字檔
內有400多萬筆資料
資料格式如下
Lon Lat Time Height Temperature
121 23.5 1985-03-13T12:00:00 10 25
121 24 1986-03-13T12:00:00 10 28
.
.
.
.
其問題在於當我使用textscan，我希望能在Time那行資料
把 1985-03-13 (年月日)及 12:00:00(時分秒) 給分開來
所以使用了以下的code
fid = fopen('格式.txt');
C = textscan(fid,'%f %f %s %s %f %f','headerlines',1,'delimiter','T');
fclose(fid);
得到的C{1} C{2} C{3}沒有問題
可是C{4}卻是 12:00:00 10 25
也就是在T之後的所有數值都當成了一個字串
想問說有沒有辦法在textscan時，也就是匯入資料的同時
就將Time這行資料拆解成兩個字串?
在這裡先謝謝把文章看完的各位...
