/**
* @defgroup VarianceExample Variance Example
*
* \par Description:
* \par
* Demonstrates the use of Basic Math and Support Functions to calculate the variance of an
* input sequence with N samples. Uniformly distributed white noise is taken as input.
*
* \par Algorithm:
* \par
* The variance of a sequence is the mean of the squared deviation of the sequence from its mean.
* \par
* This is denoted by the following equation:
* <pre> variance = ((x[0] - x') * (x[0] - x') + (x[1] - x') * (x[1] - x') + ... + * (x[n-1] - x') * (x[n-1] - x')) / (N-1)</pre>
* where, <code>x[n]</code> is the input sequence, <code>N</code> is the number of input samples, and
* <code>x'</code> is the mean value of the input sequence, <code>x[n]</code>.
* \par
* The mean value <code>x'</code> is defined as:
* <pre> x' = (x[0] + x[1] + ... + x[n-1]) / N</pre>
*
* \par Block Diagram:

* \image html Variance.gif

* \par Variables Description:

* \li \c testInput_f32 points to the input data
* \li \c wire1, \c wir2, \c wire3 temporary buffers
* \li \c blockSize number of samples processed at a time
