I want to calculate the probability density function of an image. can you tell me what is the matlab function

Assuming you mean the pdf of gray levels, use imhist().

MATLAB: Nakagami Distribution

Hi, If you have the Statistics Toolbox, you can use histfit() with the 'nakagami' option.

You can also use mle() with the 'nakagami' option to get the maximum likelihood estimates of the parameters of the Nakagami distribution.

MATLAB: How to plot different probability distribution for an image . Kindly help me.

gray_image=rgb2gray(imread('image_test.jpg'));
[r c]=size(gray_image);
pix_prob_normal=imhist(gray_image)./(r*c); 
plot(0:255,pix_prob_normal);
xlabel('Gray Levels');
ylabel('Pixels Probability');

I need to plot different type of PDF(weibull, log normal, Rayleigh etc.) for an sonar texture image

pix_prob_weibull=
plot(.....)
hold on;

so on...

At last use Legends

Hope you can do the other plots.
