Hello,

I tried to use the function fitdist. The only result is an error:

Undefined function ‘fitdist’ for input arguments of type ‘double’.

Error in FitaNormalDistributiontoDataExample (line 13)
pd = fitdist(x,’Normal’)

This was the result of running the code from help file: C:Users…DocumentsMATLABExamplesFitaNormalDistributiontoDataExampleFitaNormalDistributiontoDataExample.m

%% Fit a Normal Distribution to Data

% Copyright 2015 The MathWorks, Inc.

%%
% Load the sample data. Create a vector containing the patients’ weight data.
load hospital
x = hospital.Weight;

%%
% Create a normal distribution object by fitting it to the data.
pd = fitdist(x,’Normal’)

%%
% Plot the pdf of the distribution.
x_values = 50:1:250;
y = pdf(pd,x_values);
plot(x_values,y,’LineWidth’,2)
