I'm quite new for MATLAB. Anybody knows how to deal with the problem?
tq = interp3(x,y,z,tem,xq,yq,zq);
x,y and zq are in interp01.zip
tem and xq are in interp02.zip
yq and z are in interp03.zip
Every suggestions will be appreciated.

Hi,
I think this error may be due to two reasons:
  1. The input arguments x, y, z to the interp3 function must be either grid vectors or a full grid. You can try using ‘meshgrid’ function to create these arrays.
  2. The arguments xq, yq, zq must be either scattered points or grid vectors or scalars.
Refer to the following documentation page for additional information: https://www.mathworks.com/help/matlab/ref/interp3.html#bt2rbzl-4
