## Contents

## Usage

NvB = calcNvB(N, v, B, opt, ii)

## Input

* N*: shape functions

* v*: velocity

* B*: shape function derivatives

* opt*: option structure. for details see Assemble_LHS_std

* ii*: in case of nested calculation this defines which loop well be calculated. (Currently this is not used)

## Output

* NvB*: the product N x v x B computed in vectorized manner
