[問題]解聯立方程式 已回收
部分的程式碼在下面，怎麼聯立解出兩個方程式的u(i),y(i)?
我試過solve可是沒辦法解出來耶
是否是裡面變數太多？
while y(i)>=eps
i = i+1; %Increment the counter
Reu = (p*d*u(i-1))/(mu);
Rev = (p*d*v(i-1))/(mu);
u(i)=(u(i-1)*(1 - Cd*Reu*dt/(48*tau)-Cl*Rev*(v(i-1)+v(i))*dt/48*tau)) / (1 +Cd*Reu*dt/(48*tau));
v(i)=(v(i-1)*(1 - Cd*Rev*dt/(48*tau)) - g*dt + Cl*Reu*(u(i-1)+u(i))*dt/48*tau)/ (1 + Cd*Rev*dt/(48*tau));
x(i) = x(i-1)+(dt/2)*(u(i-1)+u(i));
y(i) = y(i-1)+(dt/2)*(v(i-1)+v(i));
t(i) = s + (i-1)*dt;
開頭宣告過有關的變數有
i = 1;
Cd = 0.27;
Cl = 0.165;
g = 32.2;
dt = 0.04;
w = 1.5/16;
d = 1.75/12;
p = 0.002378;
mu = 0.375*10^(-6);
m = w/g;
tau = m/(3*mu*pi*d);
拜託各位高手幫忙解答了!!!!
謝謝
