so I used the distribution fitter app to find the best PDF for my data and i found the best fit to be the beta pdf. i then saved the pdf parameter to my workspace.

and when i exctract the parameters they come in this form:

Beta distribution

a = 0.488112 [0.385556, 0.617948]

b = 1.3023 [0.817649, 2.07421]

how can i only exctract a and b.

在 MATLAB Online 中打开

If your save object is mybetaObject then

myBetaObject.ParameterValues % both a, b

or

myBetaObject.a                
myBetaObject.b

for each. Hard to glean from the doc if use the app; see the description of the fitted distribution objects throuth the fitdist doc link for each distribution.
