function [dydt] = diffvar(t,y)
dydt=-k*y+a;
end
end
in this if a is vector how to solve

If k and a are constant vectors of equal length the following will work
k = rand(10, 1);
a = rand(10, 1);
IC = zeros(10, 1);
tspan = [0 10];
[t, y] = ode45(@(t,y) diffvar(t,y,k,a), tspan, IC)
plot(t, y)
function [dydt] = diffvar(t,y,k,a)
dydt=-k.*y+a;
end
