Hi. I want to solve a equation in matlab, and wrote the attached file. but it has an error! Thank you.
% marcov chain
format long
syms s
syms l c sigma u
p2=(u*p1+1)/(s+l+sigma);
p1=((cl+sigma)*p2+2*u*p3)/(s+u+l);
p3=((1-c)*l*p2 + l*p1)/(s+2*u);
Availability=p1+p2;
% safety=p2+p1;
f=ilaplace(availability);
u=0.01;
l=0.0001;
c=0.95;
sigma=0.000001;
for i=1:100
time(i)=i*500;
t=time(i);
result(i)= double(subs(f));
end
plot (time,result)

you define Availability (capital A), but then use availability (small a)
