* \par Description:
* \par
* Demonstrates the use the Maximum Minimum Mean Standard Deviation Variance
* and Matrix functions to calculate statistical values of marks obtained in a class.
*
* \note This example also demonstrates the usage of static initialization.
*
* \par Variables Description:
* \par
* \li \c testMarks_f32 points to the marks scored by 20 students in 4 subjects
* \li \c max_marks Maximum of all marks
* \li \c min_marks Minimum of all marks
* \li \c mean Mean of all marks
* \li \c var Variance of the marks
* \li \c std Standard deviation of the marks
* \li \c numStudents Total number of students in the class
