sqrtm            Scilab Group            Scilab Function              sqrtm
NAME
   sqrtm - matrix square root
  
CALLING SEQUENCE
 y=sqrtm(x)
PARAMETERS
 x          : real or complex  square matrix
            
DESCRIPTION
   y=sqrt(x) is the matrix square root of the x x matrix (x=y^2) Result may
  not be accurate if x is not symmetric.
  
EXAMPLE
 x=[0 1;2 4]
 w=sqrtm(x); 
 norm(w*w-x)
 x(1,2)=%i;
 w=sqrtm(x);norm(w*w-x,1)
SEE ALSO
