Moving average in C++

The function moving average uses only standard library headers, also uses dynamic memory to allocate the correct size of the array to do the average.

Usage of the function

Import the header

#import "filters.h"

Then, create a new instance of the filter and initialize it according to the number of samples required, assuming that all the samples start in 0.

movingAverage mean1;
mean1.numberOfSamples = 100;

mean1.initialize();

The function initialize could be used to test if the memory allocation is successful.

if(mean1.initialize())
{
   cout << "Successful initialization" << endl;
}
else
{
   cout<< "No memory remaining" << endl;
   return 0
}

The function mean() will return the average of the data samples:

cout << mean1.mean(1);

See testMoving.cpp for a short implementation.
