how to solve Polynomial multiplication of vector

[huicai__xiang]

Hi.

I'm looking for a function in MKL or IPP or other related libraries
that does element-wise multiplication on vector and matrix.

vector [a1, a2, a3, ...am]

matrix b

[b11, b12, b13, ...b1m

b21, b22, b23, ...b2m

...

bn1, bn2, bn3, ...bnm]

result =

[(a1^0*b11 + a1^1*b21+... + a1^(n-1)*bn1)，

(a2^0*b12 + a2^1*b22+... + a2^(n-1)*bn2),

...

(am^0*b1m + a2^1*b2m+... + a2^(n-1)*bnm),

]

The elements will be floating point numbers (doubles or floats).

I searched the MKL and IPP documentations,
but could not find the function that does this operations.
Is there a function for this?
Thanks.

Here is the reference guide to multiply the elements of two vectors in IPP:

IPP does not support matrix multiplication operations, please use MKL for this.
