 '''coef''' ''NBU'' [ ''BU<sub>1</sub>'' ''BU<sub>2</sub>'' ... ] 
          [ ''NBR<sub>1</sub>'' ''BR<sub>1,1</sub>'' ''BR<sub>1,2</sub>'' ... ]
          [ ''NBR<sub>2</sub>'' ''BR<sub>2,1</sub>'' ''BR<sub>2,2</sub>'' ... ]
          ...
Defines the coefficient matrix for the automated burnup sequence. Input values:

{|
| <tt>''NBU''</tt>
| : number of burnup points
|-
| <tt>''BU<sub>n</sub>''</tt> 
| : burnup steps at which the branches are invoked (positive value = burnup [in MWd/kg], negative value = time [in d])
|-
| <tt>''NBR<sub>m</sub>''</tt>
| : number branches in the ''m''-th dimension of the burnup matrix
|-
| <tt>''BR<sub>m,i</sub>''</tt> 
| : name of the ''i''-th branch in the ''m''-th dimension
|}

<u>Notes:</u>

*The coef card creates a multi-dimensional coefficient matrix (of size <tt>''NBR<sub>1</sub>''</tt> &times; <tt>''NBR<sub>2</sub>''</tt> &times; <tt>''NBR<sub>3</sub>''</tt> &times; ... ). 
**The automated burnup sequence performs a restart for each of the listed burnup points, and loops over the branch combinations defined by the coefficient matrix. 
*The coef card is used together with the [[#branch|branch]] card.
*For multiple historical variations or historical conditions defined using a [[#branch|branch]] card, see the [[#casematrix|casematrix]] card.
