Declaration
func vDSP_vthr(_ __A: UnsafeParameters
__ASingle-precision real input vector
__IAStride for
A__BPointer to single-precision real input scalar: lower threshold
__CSingle-precision real output vector
__ICStride for
C__NThe number of elements to process
Discussion
Performs the following operation:
for (n = 0; n < N; ++n){
if (A[n*IA] >= *B)
C[n*IC] = A[n*IA];
else
C[n*IC] = *B;
}
Creates vector C by comparing each input from vector A with scalar *B. If an input value is less than *B, *B is copied to C; otherwise, the input value from A is copied to C.
