Problem with inv function |

Hello,
I am inverting a big matrix (60x60) using the inv function. The result of
the inversion is a matrix with the first column with a number in the first
row and the rest of the rows with zeros. I have inverted this matrix using
other application and the result of the inversion is different, the first
column doesn't have zeros in the whole column except the first row. The
multiplication of the original matrix by each inverted matrix is the
identity matrix, but I don't understand why the inverted matrix is
different. Why octave produces this result?
Thanks.
