How do i get the CDF and ICDF functions to accept a variable instead of just numbers.

Not sure what exactly is going on, when i plug in actual number for an upper and lower boundries into the icdf function it works fine but if i use variables with the exact same values it doesn't work, i get an empty matrix.

cdf_upper_bound = .10;
cdf_lower_bound = .20;

z = icdf(D_obj.n , [.10:0.01:.20])'

Unable to resolve the name D_obj.n.

K>> load D_obj
K>> fieldnames(D_obj)
ans =
  3×1 cell array
    {'k'}
    {'n'}
    {'w'}
K>> 

The field name is lowercase "k", not uppercase "K". MATLAB is case-sensitive.

Thats not it, maybe i misstyped it here but the code actually computes it just doesnt generate the same result.

The same result as what?

You're going to have to give a minimum working example that illustrates the problem you think you have.

The contents of D_obj are three different distribution functions; what are you comparing to what?

Here is a screencap, I wound think z and k would output the same values since all the arguments/range are equal but as you can thats not the case here.

Apologies if i was vague.

Opps, just realized i crossed my variable. that was the issue. thanks for taking a look though.

I was pretty sure had to be something of the sort...glad you found it.
