Neonfloat32x4_tvmulq_laneq_f32(float32x4_t a, float32x4_t v, const int lane)Scalar arithmetic / Vector multiply by scalar
Description
Floating-point Multiply (vector). This instruction multiplies corresponding floating-point values in the vectors in the two source SIMD&FP registers, places the result in a vector, and writes the vector to the destination SIMD&FP register.
Results
