5.3 Positioning Arrays in Memory

In dependence of the data location in memory, the execution time of the program can vary significantly. Choice of convenient data structure is very important for current using the data from the cash memory. Our program operates with complex functions, which can be stored in two different ways: as two real arrays for real and imaginary parts, respectively, or as one complex array.
