Reading data from .txt file into Matlab

I have been trying in vain for days to do one seemingly simple thing--I want to read data from a .txt file that looks like this:

    0.221351321
    0.151351321
    0.235165165
    8.2254546 E-7

into Matlab. I've been able to load the data in the .txt file as a column vector using the fscanf command, like so:

    U=fscanf(FileID, '%e')

provided that I go through the file first and remove the space before the 'E' wherever scientific notation occurs in the data set.

Since I have to generate a large number of such sets, it would be impractical to have to do a search-and-replace for every .txt file.

Is there a way for matlab to read the data as it appears, as in the above example (with the space preceding 'E'), and put it into a column vector?

For anyone who knows PARI-GP, an alternate fix would be to have the output devoid of spaces in the first place--but so far I haven't found a way to erase the space before 'E' in scientific notation, and I can't predict if a number in scientific notation will appear or not in the data set.

Thank you!

Solution

  • Thank you all for your help, I have found a solution. There is a way to eliminate the space from PARI-GP, so that the output .txt file has no spaces to begin with. I had the output set to "prettymatrix". One needs to enter the following:

        ? \o{0}

    to change the output to "Raw," which eliminates the space before the "E" in scientific notation.

    Thanks again for your help.
