i have an excel sheet of data having (400x256). The columnsn of each row B,D, F, F+2, F+4,..... till 256 having value either 80 or 90. i want to replace those values with "pass" or "fail".
I am using matlab 2018a. so i am using xlsread/xlswrite funtions.
I tried the below code but it is not working...
I read the excel to a variable in matlab
data = xlsread("filename.xlsx","sheet").
then tried changing that particular cell,
if data(1,2) == 80
data(1,2) = "pass"
then write back the data to excel.
xlswrite("filename.xlsx", data, "sheet")
but i don't see "pass" in B1 cell instead seeing an empty cell.

this is my suggestion - convert your data (numeric double) to cell array first
and more robust if statement as numerical round off can cause some issues it you do "strict" comparison with the given value (here 80), so use a tolerance to account for this
data = xlsread('filename.xlsx','sheet');
cellarray = num2cell(data);
tol = 1e-12;
% then tried changing that particular cell,
if abs(cellarray{1,2} - 80) < tol
cellarray{1,2} = "pass"
% then write back the data to excel.
xlswrite('filename.xlsx', cellarray, 'sheet')

In your case you are creating a NaN, as your "data" is only numeric.
