    observe matrix M:

    Prime has a rows selector, [Ctrl-Shft-R], and to select the first row:

    And a column selector [Ctrl-Shft-C], and to select the first column:

    Note how the angle brackets around the 0 differ.

    Now compare  that to your two programs for f1 and f2.

     

    Success!
