Why does my index exceed array bounds for the following for loop?

lamda = 0:500; %s^-1
mewp = .012; %Poise
for i = 1:length(lamda)
    mewapp = mewp(2.3409.*lamda(i) + 6.12.*sqrt(lamda(i))+4);
    figure(1)
    hold on
    plot (lamda(i),mewapp);
end

error message

Index exceeds array bounds.

Error in Problem3_b (line 4)

mewapp = mewp(2.3409.*lamda(i) + 6.12.*sqrt(lamda(i))+4);

You don’t need a loop

mewp*
  % ^-—-—-missed it

[madhan ravi]

lamda = 0:500; %s^-1
mewp = .012; %Poise
mewapp = mewp*(2.3409*lamda + 6.12*sqrt(lamda)+4);
plot (lamda,mewapp)

If you want to see the movement of the plot:

figure
comet(lamda,mewapp)
