If either mu or sigma is a scalar, then normrnd expands the scalar argument into a constant array of the same size as the other "custom" — A moving average using a custom method is a type of moving average that uses a custom measure of weights to calculate the average, instead of just taking the close price of each bar as most other moving averages do. If both mu and sigma are arrays, then the array sizes must be the same. We can pass a second argument as ‘2’ if we need the average along the rows of the matrix.
