Neonfloat64x1_tvmul_n_f64(float64x1_t a, float64_t b)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.
