You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: CheckPairsXZ.m
    path of file: ./repos/2D_3D_PolarFourierTransform/MATLAB CodeBase/NVIDIA_3DSphericalDFT
    
    the code of the file until where you have to start completion: function IsPresent = CheckPairsXZ(k,m, K,M )

%% Extra coding for XX ,YY , XZ and YZ blocks seperate conditional computations
% No of levels theta                           % These computed on fly

    
function IsPresent = CheckPairsXZ(k,m, K,M )

%% Extra coding for XX ,YY , XZ and YZ blocks seperate conditional computations
% No of levels theta                           % These computed on fly
P = (K-2)/4;                                   % Number of levels
if(rem(K-2,4) ~= 0)
    P = ceil (P);                           % use + 1 to compute for 45 but skip for other dimension
