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.
