FVector.join constructor
Builds a new FVector composed from multiple other FVector's
Implementation
factory FVector.join(List<FVector> vectors) {
int nRows = vectors.fold(
0, (int previousValue, element) => previousValue + element.nRows);
Float32List newColumnData = Float32List(roundUp4(nRows));
int currentVec = 0;
int src = 0;
for (int dest = 0; dest < nRows; ++dest) {
while (src == vectors[currentVec].length) {
src = 0;
currentVec++;
}
newColumnData[dest] = vectors[currentVec][src];
src++;
}
return FVector.fromBuffer(nRows, newColumnData.buffer.asFloat32x4List());
}
