Does MKL have equivalent function as ARPACK/s znaupd ?

I am wondering whether MKL has equivalent function as znaupd/zneupd.
This is part of the code I would like to use MKL to replace ARPACK:

while (ido != 99)

{

znaupd_(ido, bmat, n, which, k, tol, resid, p, v, n, iparam, ipntr, workd, workl, lworkl, rwork, info);

...

switch(ido)

{

case -1:

case 1:

zgemv_(trans, n, n, alpha, a, n, workd+2*(ipntr[0]-1), incx, beta, workd+2*(ipntr[1]-1), incy);

break;

...

}

}// while (ido ~= 99)

...

...

zneupd_(rvec, howmny, select, d, z, n, sigma, workev,

bmat, n, which, k, tol, resid, p, v, n, iparam, ipntr,

workd, workl, lworkl, rwork, info);//same as for znaupd

You ought to be able to link against MKL to replace any BLAS functions called by ARPACK. If you have BLAS source code in your project, e.g. ?gemv, you would simply drop those functions and permit MKL to replace them.

This is not what I want. I prefer to link with MKL only, so I don't need to link to another library, especially as ARPACK is built with other programming language and other reasons.

This is a commonly used function. I wonder whether MKL support it.
