# subsToArray

## PURPOSE

Converts subs/vals image representation to array representation.

## SYNOPSIS

function I = subsToArray( subs, vals, siz, fillVal )

## DESCRIPTION

     Converts subs/vals image representation to array representation.

     Constructs array from subs/vals representation.  Similar to Matlab's
     sparse command, except doesn't actually produce a sparse matrix.  Uses
     different conventions as well.

     USAGE
      I = subsToArray( subs, vals, siz, [fillVal] )

     INPUTS
      subs    - subscripts of point locations (n x d)
      vals    - values at point locations (n x 1)
      siz     - image size vector (1xd) - must fully contain subs
      fillVal - [0] value to fill array with at nonspecified locs

     OUTPUTS
      I       - array of size siz
