1) It is necessary to transfer matlab function medfilt1 to C++ Qt.
2) It is required to make refactoring of the following functions: median; max; std; find; diff; sum; mean if it allows to accelerate their performance.
The result of performance of all functions on C++ Qt has to coincide with result of performance in Matlab.
It is desirable without use of third-party libraries though their application can be discussed.
In an investment the class matlabFunctions (.h and .cpp) with which need to work in Qt Creator 4.8 (Qt 5.12).
