rcond            Scilab Group            Scilab Function              rcond
NAME
   rcond -  inverse condition number
  
CALLING SEQUENCE
 rcond(X) 
PARAMETERS
 X    : real or complex square matrix
      
DESCRIPTION
   is an estimate for the reciprocal of the condition of X in the 1-norm.
  
   If X is well conditioned, rcond(X) is close to 1. If not, rcond(X) is
  close to 0.
  
   sets r to rcond(X) and returns z such that
  
   Thus, if rcond is small z is a vector in the kernel.
  
EXAMPLE
 A=diag([1:10]);
 rcond(A)
 A(1,1)=0.000001;
 rcond(A)
