I understand that you want to access the values of N, M using k, g as your indices.
You can exploit MATLAB’s logical indexing for this application.
The Structure definition is right on track for this purpose.
Assuming you have defined the structure in your question accurately, first column is k, second column is N, followed by a cell array with g, M.
The following code might be helpful
%Define your structure
Struct = {1,92,{'a',999;'cc',555;'de',44};...
2,61,{'a',666;'cc',33;'de',777};...
3,54,{'a',105;'cc',300;'de',46};...
6,106,{'a',55;'cc',666;'de',33};...
10,23,{'a',88;'cc',44;'de',111}}
%Structure is defined
%define the variables g and k
g=6;
k='a';
cellArray=Struct{cell2mat(Struct(:,1))==k,3}; %spotting the corresponding cell array
logicalCellArray=strcmp(cellArray,'de'); %converting the cellArray to a Logical table
M=y{logicalCellArray,2}; %obtaining the value of M
N=Struct{cell2mat(Struct(:,1))==k,2} %Obtaining the value of N
This can be consized to 2 lines of code, but this code if for your understanding of the algorithm.
