Hi there,
I have a matrix say 5*5. The matrix contain some numerical values with many digists shown in scientific notation.
I would like to write this matrix to a text file without any scientific notation. Using "format long " only changes the display and matlab still writes in scientific notation to the text file.
How can i fix this ?

You can use dlmwrite() and pass in a 'precision' option that is a character vector representing a % format. For example, you could use '%13.6f' if you wanted at least 13 total locations with 6 after the decimal point.
