Greetings,

As writen above i would like to be able to plot values of 'u'that comes out from for loop so i need somehow to put them in a form of a vector or whatever form suits the best.but cant figure out the code for that. my code:

umax=0.54; M=-4.2703; D=1.8;

for y=0:.1:1.8;

u=umax/M*log(1+(exp(M)-1)*(y/D)*exp(1-y/D))

end

disp(u)

tyvm in advance.

在 MATLAB Online 中打开

Y = 0:.1:1.8;
n = length(Y);
u = zeros(n,1);
for k=1:n;
  u(k)=umax/M*log(1+(exp(M)-1)*(y(k)/D)*exp(1-y(k)/D))
end

that was really quick. than u very much guys.

Yours solutions worked like a charm. But on John response I can't really figure out how u=zeros(n,1) gives a values of u that are non zeroes on output, although it does.
