without for loop

ttechnik: without for loop

Why would you not use a for loop?

Not compiled, not tested.

void Fill2D1D(double a2d[][], int e2d, double a1d[], int nElem=EMPTY, int iBeg=0){
   if(nElem == EMPTY) nElem = ArraySize(a1d) - iBeg;
   for(int iLimit = iBeg + nElem; iBeg < iLimit; iBeg++)
      a2d[iBeg][e2d] = a1d[iBeg];
}
/////////
double acr[][6]; ArrayResize(acr, n);
double a1d[];    ArrayResize(a1d, n);  Fill1D(a1d ...);
Fill2d1d(acr, 2, a1d); // acr[x][2] == a1d[x] for x=[0..n-1]

Thank you very much.

I think it has a standard array function.

I do not know how slow it is

Tested:

void FillxDWith1D(double& axd[][], int exd, double a1d[], int nElem=EMPTY, int iBeg=0)
 {
  if(nElem == EMPTY) nElem = ArraySize(a1d) - iBeg;
  int iLimit = iBeg + nElem;
  
  for(; iBeg < iLimit; iBeg++)
   axd[iBeg][exd] = a1d[iBeg];
 }
