subsref

Evaluate the spline with function-call syntax or defer to built-in indexing.

---

Declaration

 varargout = subsref(self,index)

Parameters

• self BSpline instance
• index MATLAB subscript structure

Returns

• varargout indexed property access or spline values

Discussion

Parentheses indexing spline(t) is redirected to valueAtPoints(...), while dot indexing behaves like the default MATLAB handle-class implementation.

Use spline(t) for values. For derivatives, use valueAtPoints(t, D=...).

  x = spline(tQuery);
  dxdt = spline.valueAtPoints(tQuery, D=1);
