Question

I have files which have many empty cells which appear as NaNs when I use cell2mat, but the problem is when I need to get the average values I cannot work with this as it shows error with NaN. In excel it overlooks NaN values, so how do I do the same in MATLAB?

In addition, I am writing a file using xlswrite:

xlswrite('test.xls',M);

I have data in all rows except 1. How do I write:

M(1,:) = ('time', 'count', 'length', 'width')

In other words, I want M(1,1)='time', M(1,2)='count', and so on. I have data from M(2,1) to M(10,20). How can I do this?

Answer 1

Use ‘ isfinite ‘ function to get rid of all NaN and infinities

A=A(isfinite(A))

%create the cell array containing the column headers
columnHeader = {‘Column 1’, ‘Column 2’, ‘Column 3’, ‘Column 4’, ‘Column 5′,’ ‘};

%write the column headers first
xlswrite(‘myFile1.xls’, columnHeader );

% write the data directly underneath the column headers
xlswrite(‘newFile.xls’,M,’Sheet1′,’A2′);
