MATLAB: Matlab does not plot the function, why

matlab function

Hi want this function to plot but i'm getting no error or a curve…

rLP = 0:1:200;

PrL = rLP * 9 /(rLP+12);

plot(rLP, PrL); grid;

You need to do element-wise division (use ‘./’ instead of ‘/’:

PrL = rLP * 9 ./ (rLP+12);

See the documentation on Array vs. Matrix Operations (link) for detials.

   d=c(:)'

%f true
 num = [1.077e4]
den = [3.439e-7 1 0]

Enter the vectors num and den coefficients in the transfer function block. See the below resource
