<div>Hi,</div>
<div>Is there a filter that can interpolate unstructed data to structed data? like griddata() in MATLAB.</div>
<div> </div>
<div>for example: </div>
<div>i know three points: a(1,1)=1; a(1,3)=2; a(3,3)=3;</div>
<div>how can I interpolate the data so that i can get a(1:3,1:3)?</div>
<div><br clear="all"><br>-- <br>Best wishes,<br>Jiangshan </div>
