i have 3d data for resolution 2.0*2.5 but i want to interpolate this data set on .25*.25 resolution.

for this i already written this code. please tell this code is write or wrong for this process.

x = 68.7500; y = 7;

 for i = 1:120
     x_new(i,1) = x;
     x = x + 0.25;
 end
 for j = 1:128;
     y_new(j,1) = y;
     y = y + 0.25;
 end
 [x,y] = meshgrid(Y1,X1);
 [x1,y1]=meshgrid(y_new,x_new);
 method='linear';

for i=1:12810;

interpolate_data(: , : , i) = interp2(x,y,model_data(: , : , i),x1,y1,method);

end
