Question

u and v and r should be vectors.

function [g] = kast(m,k,u,v,n)
g = 9.80;
t = 0:0.1:n;
r = [u.*(m/k).*(1-exp(-k.*t./m),((-m*g/k).*t) + (v.*(m/k).+m^2*g/k^2).*( 1.-exp(-k.*t./m)))];

plot(t,r)
end

I’ve spent about an hour, but I cannot work out what is wrong. Are any of you able to spot my error?

Thank you for your time.

Kind regards,
Marius

Answer 1

.+m^2

looks suspicious. Try remove the dot before the +. And add a closing bracket before the comma in the assignment of r.
