I have a problem. I have attached an excel file to make you understand what I have to do:
I have to get in matlab a table/structure equal to the one present in this attached excel, in the sheet called "coord_lambda". I need this arrangement because then I have to do other calculations with these values.
this sheet is made up of coordinates and lambda values ​​(each lambda value is associated with two coordinates) which are found in two other sheets ("coord" and "lambda"). the coordinates are divided by colors where the orange ones must be entered from row 3c, while the yellow ones must be entered in the first and second column starting from row 4 (A4-B4). the lambda values ​​("lambda" sheet) instead must be entered in the table alternately (blue and green colors) as in the "coord_lambda" sheet: in column order A-I-B-J-C-K-D-L-E-M-F-N-G-O-H-P. column A of "lambda" must be inserted from cell C4 in "coord_lambda" and so on.
is it possible to do this? Can anyone help me?

C=readmatrix('esempio.xlsx','Sheet','coord'); % get inputs...
L=readmatrix('esempio.xlsx','Sheet','lambda');
N=size(L,2)/2; % figure output array size
M=size(C,1);
CL=nan(M-N+1,2*N+2); % preallocate output array
CL(1,3:end)=reshape(C(1:N,1:2),1,[]); % first row coordinates from beginning coordinates
CL(2:end,1:2)=C(N+1:end,1:2); % then fill in first two columns of coordinates
CL(2:end,3:2:end)=L(:,1:N); % Left, then
CL(2:end,4:2:end)=L(:,N+1:end); % right of field data alternating columns
vNames=["lam_L"+(1:N); "lam_R"+(1:N)]; % build variable names for table
vNames=["coord"+[1:2] vNames(:).']; % produce "L/R" sequence for lambda
tCL=array2table(CL,'VariableNames',vNames); % resulting table matching spreadsheet layout
produces close facsimile...
