variableAtPositionWithName

Access dynamical variables at arbitrary positions in the domain.

---

Declaration

 [varargout] = variableAtPositionWithName(x,y,z,variableNames,options)

Parameters

• x array of x-positions
• y array of y-positions
• z array of z-positions, or empty for two-dimensional variables
• variableNames strings of variable names.
• options.interpolationMethod periodic linear or cubic spline interpolation; default linear

Returns

• varargout interpolated arrays in the requested order and query shape

Discussion

Computes (or retrieves from cache) any known state variables and computes their values at the requested positions (x,y,z). For two-dimensional variables, interpolation uses only (x,y), and z may be empty.

The interpolation method may be linear or spline. Horizontal coordinates are wrapped periodically before interpolation.

[u,v] = wvt.variableAtPositionWithName(xParticle,yParticle,zParticle,'u','v',interpolationMethod='spline');
