[Scilab-users] a linear equation

[fujimoto2005]

I am trying to solve linear equations with 30 variables. Since the
determinant of the coefficient matrix is 0, I can tell that some row vectors
are linearly dependent on other row vectors. I want to solve the problem by
deleting the linearly dependent rows while simultaneously changing the
variables to exogenous variables.
But I can't find which row vector expresses redundant constraints.  
Is there any way to find out which row is linearly dependent?

Best regards.
