Matlab Enframe function C + + implementation

MATLAB uses the enframe to deal with the speech signal in the speech processing.

I looked over the internet for some information about Enframe:

Y=enframe (X,framelength,step);

X is the signal vector, which can be a heading or a column vector,

Framelength is the length of each frame,

Step refers to the number of samples moved between a frame and a frame, some of which are called non-overlapping lengths,

The number of frames divided is: NF = fix ((nx-framelength+step)/step),

Where NX is the length of x, Y is an array of framelength*nf or nf*framelength, depending on whether X is a row vector or a column vector.

//c++ Implementation of enframe frame function
Input:
float* x: Signal source (line vector)
int Framelength: The length of each frame
int step: The number of samples moved between a frame and a frame, some of which are called non-overlapping lengths
//
Output:
A number of frames * Two-dimensional array of each frame length



Static float* * Enframe (Const floatX[],intSrclength,intFramelength,intStep) {    intNF = Floor ((srclength-framelength + Step)/step);//figure out the number of frames    float* * YENFRAME;//used to store the resultsYenframe =New float*[NF];  for(inti =0; I < NF; i++) {Yenframe[i]=New float[Framelength]; }    intCount =0; intStartno =0;  while(Count <NF) {         for(inti =0; i < framelength; i++) {Yenframe[count][i]= X[startno +i]; } Count++; Startno+=step; }        returnYenframe;}
