Noise Signals. In engineering simulations, we often want to generate a floating-point sequence of values with a specified mean and variance. The function developed in Chapter allows us to generate numbers between limits a and b, but it does not allow us to specify the mean and variance. By using results from probability, we can derive the relationship between the limits of a uniform random sequence and its theoretical mean µ and variance σ2:

Write a function named rand_mv that generates a random floating-point value with a specified mean and variance that are input parameters to the function. Assume that the corresponding function prototype is

double rand_mv(double mean,double var);

Use the rand_float function developed in Chapter 4.
