multiplyVector method
multiplies this matrix by a vector, resulting with new vector.
Implementation
FVector multiplyVector(FVector vec) {
assert(vec.nRows == this.nColumns);
Float32List float32list = Float32List(roundUp4(this.nRows));
for (int i = 0; i < nRows; ++i) {
Float32x4List currentRow = rowsData[i];
Float32x4 sum = Float32x4.zero();
for (int j = 0; j < currentRow.length; ++j) {
sum = sum + (currentRow[j] * vec.columnData[j]);
}
float32list[i] = sum.x + sum.y + sum.z + sum.w;
}
return FVector.fromBuffer(this.nRows, float32list.buffer.asFloat32x4List());
}
