[KALYAN ACHARJYA]

im=imread('iamge_file_name.jpg');
grayImage=rgb2gray(image1);
result=mean(grayImage);

C Code Generation from MATLAB check here

Regarding Matlab function

function output=fun_name(inputs)
......do
..do
end

I have this code in matlab:

img = imread ('test.jpg');
I = rgb2gray(img);
meanIntensityValue = mean(mean(I));
[rows, columns, depth]=size(I);

In order to convert the script so I just need to copy this to the fuction like:

function output=fun_name(inputs)
img = imread ('test.jpg');
I = rgb2gray(img);
meanIntensityValue = mean(mean(I));
[rows, columns, depth]=size(I);
end
