How write multiple data output in excel sheet using xlswrite command
显示 更早的评论
Hi All,
I want to know how can we write multiple data strings in the same excel sheet for a design simulation. As We know that whenever we specify xlswrite command it starts writing from cell A1 of the excel sheet.
Now, my problem is quite specific. I am carrying out a design calculation for a treatment works. At the end of the design calculation I am storing the variables in the excelsheet using xlswrite command. Now for a set of values of particular variable A , I want to do all the design calculations and then store them in excel sheet in different rows. How can we do it. I tried to run for loop but it always stores the data in the first row of the excelsheet so only the last set of data is available through xlswrite statement.
Program syntax is something like that
a=1 ;
b= equation1 c=equation2 d=equatio3
then finally I use xls write to write all these variables in an excelsheet.
Now for a range of values for variable a, I want to do the work and store them in the same excel sheet row wise. How can one do it . I would appreciate if someone comes up with a solution.
Regards

I don't understand. Can't you just specify a range or a particular cell where you want to save you data?

I'm not sure I udnerstand the problem either as it seems that xlswrite should provide for this functionality explicity? ([SUCCESS,MESSAGE]=XLSWRITE(FILE,ARRAY,RANGE))
Regardless, I'd avoid using xlsrwite at all (as it re-instantiates Excel with each call) and manipulate the properties (exposed by the actxserver object) of the spreadsheet directly. Code below should guide you.
try
xlApp = actxGetRunningServer('Excel.Application'); % capture existing excel application
catch ME %#ok
xlApp = actxserver('Excel.Application'); % instantiate new excel application
end
xlApp.Visible = 1;
xlWorkbook = xlApp.workbooks.Open(fullfile(xlFilePath,xlFileName),0,true);
xlSheets = xlWorkbook.Sheets;
xlSheetNamesArray = cell(xlSheets.Count,1);
for i = 1:xlSheets.Count
xlSheetNamesArray{i} = xlSheets.Item(i).Name; % sheet-order is not guaranteed so must build array
end
[~,idx] = ismember('Price',xlSheetNamesArray);
xlSheets.Item(idx).Activate
xlActiveSheet = xlWorkbook.ActiveSheet;
xlCurrRange = xlActiveSheet.Range('C4:C33');
priceVector = xlCurrRange.Value2;
priceVector = cell2mat(priceVector);
[~,idx] = ismember('Portfolios',xlSheetNamesArray);
xlSheets.Item(idx).Activate
xlActiveSheet = xlWorkbook.ActiveSheet;
xlCurrRange = xlActiveSheet.Range('B4:B22');
isinVector = xlCurrRange.Value2;
xlCurrRange = xlActiveSheet.Range('C3:G3');
ptfNumVector = cell2mat(xlCurrRange.Value2)';
xlCurrRange = xlActiveSheet.Range('C4:G22');
dataMatrix = xlCurrRange.Value2;
isnanMatrixMask = strcmp(dataMatrix,'ActiveX VT_ERROR: '); % handle missing data - assume as no position
dataMatrix(isnanMatrixMask) = {0};
dataMatrix = cell2mat(dataMatrix);

Have you actually read the documentation?
xlswrite(filename,A,sheet,range)
That does what you ask for. Or am I missing something? Also Mark gave a good answer to your question that avoids the overhead of repeated calls to xlswrite() that have the potential to slow down your code considerably.

Hi, this is what is needed
a=5 b=4 c=10 d= a*b; e= b*c; f= d*e;
offset =1;
for a_iter 1:5
a = a_iter; b= 4*a_iter;c = 10*a_iter; d= a*b; e= b*c; f= d*e;
xlswrite('filename.xls', [a b c d e], 1, sprintf('A%d',offset));
offset = offset + 1;
end
It will print in the A1 row for first time. and then go to next row by this sprintf('A%d',offset);

Hi Vijay,
What if the answers to be written in the excel file are in column and not rows how do I write the code for the xlswrite().
Thanks

I have created a new post. I hope you can now answer me for it. The link for that questions is :
Looking forward for your reply and suggestions on it

I wish to run the program 3 times, and each time I want to save data in a same excel sheet but to the new row. Will it be possible to do?
Thanks.
