function [ varargout ] = minmaxsubd( varargin )
%MINMAXSUBD Calculate subdomain minima and maxima.
%
%   [ MIN_VAL, MAX_VAL, MIN_COORD, MAX_COORD ] = MINMAXSUBD( S_EXPR, PROB, IND_S, IND_C, I_CUB, SOLNUM )
%   Evaluates the mimimum and maximum value of expression S_EXPR over the
%   subdomains indicated in IND_S or alternatively the cells in IND_C.
%   PROB is a valid finite element problem struct. Returns the minima and
%   maxima in MIN_VAL and MAX_VAL, and the corresponding coordinates in
%   MIN_COORD and MAX_COORD.
