plot when a value of zero makes issue
显示 更早的评论
my code below is supposed to plot different graph with different value of t:
many thanks
c=2;
nu = 1*1e-6;
r = linspace(0,100);
t=[1/2 1 2 6 10 20 50 ];
for count=1:7
v = c * (1-exp(-r.^2./(4*nu*t(count))))./r;
plot(r,v,'o-')
legend([' t= ',num2str(t(count))])
legend show
ylabel('v(m/sec)')
xlabel('r(m)')
grid on
hold on
end

If you change your nu to something more reasonable, it provides the graphs dynamics you are looking for.
nu=10;

legend show;
ylabel('v(m/sec)');
xlabel('r(m)');
grid on;

No reason to execute hold commend multiple times in the loop. Once is enough.
