[問題] 字串變數展示已回收
先謝謝大家看我的問題
我現在有兩組變數值a(i)與E(i)
舉例來說
for i = 1:10
a(i)=0.025*i;
E(i)=0.011*i;
end
現在我想在外面暫存區或是存檔成方便我copy的形式
格式是
1 {0.025,0.011}
2 {0.05,0.022}
3 {0.075,0.033}
4 {0.1,0.044}
5 {0.125,0.055}
...
前面的數字12345是方便我判斷求出來的順序
實際的值小數點後面會有很多位數所以不太會剛好尾數是零，我想取兩位就好變成
1 {0.02,0.01}
2 {0.05,0.02}
3 {0.07,0.03}
4 {0.1,0.04}
5 {0.12,0.05}
幾個困難點就是
我希望可以有大括號方便我貼在mathematica，還有就是字串裡面是變數且不能存成
矩陣形式
下面是我自己試著解決的程式碼:
for i = 1:10
a(i)=0.025*i;
if a(i)<=1
a(i)=vpa(a(i),2);
elseif (a(i)>=1) & (a(i)<=10)
a(i)=vpa(a(i),3);
elseif (a(i)>=10) & (a(i)<=100)
a(i)=vpa(a(i),4);
end
E(i)=0.011*i;
if E(i)<=1
E(i)=vpa(E(i),2);
elseif (E(i)>=1) & (E(i)<=10)
E(i)=vpa(E(i),3);
elseif (E(i)>=10) & (E(i)<=100)
E(i)=vpa(E(i),4);
end
b=([num2str(i) '{' num2str(a(i)) ',' num2str(E(i)) '}'])
end
會變成
b =
1{0.025,0.011}
b =
2{0.05,0.022}
b =
3{0.075,0.033}
b =
4{0.1,0.044}
再次謝謝大家<(_)>
