syms t s;
f=-1.25+3.5*t*exp(-2*t)+1.25*exp(-2*t)
f =
(5*exp(-2*t))/4 + (7*t*exp(-2*t))/2 - 5/4
f=laplace(f);
simplify(f);

Fourier Transform
syms a t;
x= a*abs(t);
x= fourier(x);
x1= fourier(x,y);
x2=fourier(x,t,y);
disp('1.Fourier Transform of a*abs:')
disp(x);
disp(x1);
disp(x2);

Q = @(v) sym(v);
syms t C real
alpha = Q(2);
sigma = Q(0.4);
Pi = Q(pi);
f(t) = exp(-(log(t)^2/(2*sigma^2)))/(t * sigma * sqrt(2*Pi))
eqn = C - int((t-alpha*C)*f(t), t, alpha*C, inf)
SE = simplify(eqn)
C_sol = vpasolve(SE, C)
subs(eqn, C, C_sol)
