MATLAB: Solving equations numerically

numerical

Hi everyone

Could someone help me solve the following equation numerically:

(exp(-x) + exp(-(x*exp(0.2))))/exp(0.5) = 0.8832 ?

Thanks

Best Answer

fzero(@(x)((1/exp(x) + 1/exp(x*exp(0.2))))/exp(0.5)-0.8832,pi)

MATLAB: HI I need to find gamma_t in this nonlinearal equation:

Try this:

gamma_solve = @(gamma_t,gamma_0) ei(gamma_t./gamma_0)-(gamma_0/9.022);
gamma=0:2:20;
for k1 = 1:numel(gamma)
    gamma0=10.^(gamma(k1)/10);
    GammaT(k1) = fsolve(@(gamma_t) gamma_solve(gamma_t,gamma0), 1);
end
figure(1)
plot(gamma, GammaT)
grid
xlabel('\bf\gamma\rm')
ylabel('\bf\gamma\rm_t')

MATLAB: Code for plot figure

lamda=0.2;
mu=1-lamda;
P1=mu^2/(mu+lamda)^2;
P2=2*lamda*mu/(mu+lamda)^2;
P3=lamda^2/(mu+lamda)^2;
display(P1);
display(P2);
display(P3);
t = 1:5:100 ;
P11 = zeros(size(t)) ; 
P22 = zeros(size(t)) ; 
P33 = zeros(size(t)) ; 
for i = 1:length(t)    
    P11(i)=((mu+lamda)^2)-( 2*lamda)*((mu-lamda)*exp(-(mu-lamda)*t(i))-mu+(lamda*exp(-2*(mu+lamda)*t(i))))-(lamda^2)*(2*exp(-mu*t(i))-2*exp(-(mu+lamda)*t(i))+1-exp(-2*(mu+lamda)*t(i)));
    P22(i)=((-2*lamda)*(mu-lamda)*exp(-(mu+lamda)*t(i))/(lamda+mu)^2)+(2*lamda*mu/(lamda+mu)^2)-2*(lamda)^2*exp(-2*(mu+lamda)*t(i));
    P33(i)=(lamda^2)/(lamda+mu)*((2*exp(-2*mu*t(i)))-(2*exp(-(mu+lamda)*t(i)))-exp(-2*(mu+lamda)*t(i))+1);
end
A=P11;
B=P33;
C=P22;
plot(t,A,t,B,t,C)
