ASSEMBLECONSTR Assemble integral constraints.

[ C, D ] = ASSEMBLECONSTR( PROB, ICUB ) Assemble integral constraints.

Assemble subdomain/boundary integral constraints specified in the PROB.CONSTR field. Each constr entry have TYPE (intsubd/intbdr), DVAR, INDEX (indices to subdomains/boundaries), and EXPR (resulting integrand expression, must evaluate to a numeric scalar) entries, for example

const(1).type = 'intsubd';   % Subdomain integral constraint.
const(1).dvar = 'u';         % Applied to dependent variable u.
const(1).index = [1,2];      % Applied to domains 1 and 2.
const(1).expr  = 2.3;        % Resulting integrand.
