Try these codes below please;
clc;
clear;
close all;
Data=rand(32,247);
data_mean=mean(Data,2);
plot(data_mean);
ax = gca;
exportgraphics(ax,'LinePlot.pdf')

r2 which is P has 100 rows and 2001 columns. and x_pdf giving 1 row and 991 column.
clear;
close all;
r2 = P; % Matrix which is 100x2001 double
x = r2(:,1); %can you please explain this line?
pd = fitdist(x,'Normal');
m = mean(pd);
x_pdf = [1:1:2001]; %is it correct to match the r2 column which is 2001?
y = pdf(pd,x_pdf);
figure
histogram(x,'Normalization','pdf')
line(x_pdf,y)
ax = gca;
exportgraphics(ax,'LinePlot.pdf') %showing error in this line(Error using exportgraphics

Here is the P matrix.

Let's see. I used these codes below and it did not give me error. But the 'P' matrix ' s values are pretty small. So I can not see them clearly on the graph.
x = double(P(:));
That command takes the P matrix and converts it into all column vector because fitdist() requires that.
clc; clear; close all;
load('P.mat');
x = double(P(:));
pd = fitdist(x,'Normal');
m = mean(pd);
x_pdf = [1:0.1:100];
y = pdf(pd,x_pdf);
figure
histogram(x,'Normalization','pdf')
line(x_pdf,y)
ax = gca;
exportgraphics(ax,'LinePlot.pdf')
