equalOnMask

Create a pointwise equality constraint from a logical mask.

---

Declaration

 self = equalOnMask(grid,mask,options)

Parameters

• grid vector or cell array of grid vectors
• mask logical mask selecting constrained locations
• options.D derivative orders as a scalar, row vector, or N-by-D matrix
• options.value scalar or one target value per selected point

Returns

• self equality PointConstraint

Discussion

Use this when a constrained region is naturally described by a logical mask on a rectilinear grid.

  c = PointConstraint.equalOnMask({x,y}, mask, D=[0 0], value=0);
