# MulByConj

Performs element by element multiplication of vector a element and conjugated vector b element.

## Syntax

Fortran:

call vcmulbyconj( n, a, b, y )

call vzmulbyconj( n, a, b, y )

C:

vcMulByConj( n, a, b, y );

vzMulByConj( n, a, b, y );

## Input Parameters

Name | Type | Description
--- | --- | ---
n | FORTRAN: INTEGER, INTENT(IN) C: int | Specifies the number of elements to be calculated.
a, b | FORTRAN: COMPLEX, INTENT(IN) for vcmulbyconj DOUBLE COMPLEX, INTENT(IN) for vzmulbyconj C: const MKL_Complex8* for vcMulByConj const MKL_Complex16* for vzMulByConj | FORTRAN: Arrays, specify the input vectors a and b. C: Pointers to arrays that contain the input vectors a and b.

## Output Parameters

Name | Type | Description
--- | --- | ---
y | FORTRAN: COMPLEX, for vcmulbyconj DOUBLE COMPLEX for vzmulbyconj C: MKL_Complex8* for vcMulByConj MKL_Complex16* for vzMulByConj | FORTRAN: Array, specifies the output vector y. C: Pointer to an array that contains the output vector y.
