Hi,
I have calculate the Curl, Divergence from the velocity data file available in 4650 x 4 array. Here 1, 2, 3, and 4 columns reprsents x, y, u, v. I have tried with below script, but I am getting some error. Please help..
X = data (:,1);
Y = data (:,2);
UU = data (:,3);
VV = data (:,4);
[X,Y] = meshgrid(X,Y);
[UU, VV] = meshgrid(UU,VV);
f = curl(UU,VV);

"some error" doesn't help much. Post your error so that we can help.

Your data is already gridded, no need to gridded on top of it
load('matlab.mat')
UU=reshape(data(:,3),[75 62]);
VV=reshape(data(:,4),[75 62]);
X=reshape(data(:,1),[75 62]);
Y=reshape(data(:,2),[75 62]);
close all
figure
quiver(X,Y,UU,VV);
f = curl(UU,VV);
figure
imagesc(f');
