I have a question : I am generating a excel file through matlab and i have empty cells in middle of it here is the code i am using to open a empty matrix

newfile= cell(5,5); [newfile{:}]= deal(''); [newfile{:}]= deal(' '); I do some processing here then i write xlswrite ....

now i output i get is file with some empty cells and some data. IS there a command by which i can delete the empty rows, without effecting the rows which have data?

Another question :

IS there a way to append onto this excel file i am writing. I run this file everyday and would like to add aumatically rather than me manually copying and pasting everyday.

thanks
