one way
[nt,nt,nt] = xlsread('nameyour.xlsx');
nt(cellfun(@isnan,nt)) = {256};
xlswrite('nameyour.xlsx',nt)
ON Samer's reply
eg, data:
xlswrite('Data_sheet.xlsx',[1;8;1;6;1],'B1:B5')
solution
a = 100;
[n,t,nt] = xlsread('Data_sheet.xlsx','B1:B5');
n(n == 1) = a;
xlswrite('Data_sheet.xlsx',n,'B1:B5')

He's setting those Excel cells (which are now in a MATLAB cell array called nt) that are not numbers to have the new value of 256. You can change the 256 to whatever number you want. Then it writes if back out to the same file. If you want just some submatrix (like B4..F42), then you'd have to extract that submatrix before running andrei's code on just that submatrix. Then insert the submatrix back into the full matrix and write out the full matrix.

Thank you Image Analyst! Such a good explanation difficult for me (English is not my mother tongue).
