explain a=normrnd(1,0.08); in matlab

The line a=normrnd(1,0.08); in MATLAB generates a single random number from the Normal Distribution (also known as Gaussian Distribution) with mean 1 and standard deviation 0.08.

The function normrnd takes two input arguments: mean and standard deviation. In this case, mean (or mu) is 1 and standard deviation (or sigma) is 0.08.

The output of this line is a single scalar value stored in the variable a.
