If I have a matrix of 10x200x300 double of horizontal resolution 0.25x0.25 (degrees). How can I change the horizontal resolution to 1x1 (degrees) in matlab?

NewGrid = imresize(YourGrid, 1/4);
Each pane will be done independently, so the result would be 3 x 50 x 300

My main data is 744x721x1440 (0.25x0.25 in degrees) double. Where Time = 744x1, Lat = 721x1, Lon = 1400x1. I do time averafe to it I got the resized data as 1 x 721 x 1440 (0.25x0.25 in degrees). So when I transformed the grid resolution to 1x1 (in degrees) by your mentioned process it comes as 186x181x1440. Is it ok Sir ?

YourGrid = Name_of_your_data_matrix_goes_here;
Time_Averaged_Grid = squeeze(mean(YourGrid,1));
Time_Averaged_1degree_Grid = imresize(Time_Averaged_Grid, 1/4);
