How to set up the grid in the map for 1*1 ?

Hello Sir/Madam

How set up the grid if we are having the lat and long in the respective case? I want to calculate the water volume. Can you please tell me how to set up?

• I want to set up the grid_green in the respective case. please guide me?
• I am not sure about the i and how one can define the i in the respective case?

Thank you

i=[lat;lamda];
grid_green=[i];

P_lm=legendreFunctions(grid_green(i,1)-pi/2);

You need to explain a lot better what you want to do, what you mean by 'grid', what you mean by 'case', what your inputs are, etc.

The code you've posted is nonsensical, possibly because the poorly named i variable is used for different purpose.
