I have been asked to calculate vorticity of three velocity components u,v&w. I have attached .txt file for the same. as i knew curl does the same in matlab. Hence i tried these lines of code.
u=VarName1;
>> v=VarName2;
>> w =VarName3;
>> Ulin =linspace(min(u),max(u),33);
>> Vlin =linspace(min(v),max(v),33);
>> Wlin =linspace(min(w),max(w),33);
>> [U,V,W]=meshgrid(Ulin,Vlin,Wlin);
>> [CURLX, CURLY, CURLZ, CAV] = curl(U,V,W);
when i type CURLX
all are showing zero values..

The attached file contains three columns of numbers. It is not clear how these values are connected to your question.
What is your question? If Matlab replies zeros, this is the correct result.
