Hi Shilpa,

It seems either you want to generate the histogram of an image or you want to generate a matrix which follows guassian distribution with mean 128 and variance 1689.2347.

You can generate histogram by using imhist command as

imhist(image) 

For more information refer to documentation page of imhist in the link given below:

You can generate guassian random variable using normrnd command.

A=normrnd(128, sqrt(1689.2347),[m,n]); 

For more information refer to the below link of documentation page of normrnd command:
