Dear Friends, I am facing problem in Griding data in matlab. I have written the code but its taking sooo much time to process. My data contains X(longitude) Y(latitude) Z(data points) with 0.5 degree resolution. I have to make this data gridding with 1.5x1.5 degree resolution. please help me how to save the time and also i have gone through all the griding programs in mathworks.com.
