[Q] an MKL function of the multiplication of two vectors ?
Hello,

Is there a fast MKL function of the multiplication of two vectors
 doing "for(i=0;i<n;i++) x[i]=a[i]*b[i];" ?

Thanks in advance.

Try:

Fortran:
call vsmul( n, a, b, y )
call vdmul( n, a, b, y )
call vcmul( n, a, b, y )
call vzmul( n, a, b, y )
C:
vsMul( n, a, b, y );
vdMul( n, a, b, y );
vcMul( n, a, b, y );
vzMul( n, a, b, y );

Normally, the code generated by any vectorizing compiler would be satisfactory.

Thank you.

With your advice I sought the latest MKL reference document, which included "v?mul."
