.SH NAME
det - determinant
.SH CALLING SEQUENCE
.nf
det(X)
[e,m]=det(X)
.fi
.SH PARAMETERS
.TP
X
: real or complex square matrix, polynomial or rational matrix.
.TP
m
: real or complex number, the determinant base 10 mantissae
.TP
e
: integer, the determinant base 10 exponent
.SH DESCRIPTION
\fVdet(X)\fR ( \fVm*10^e\fR is the determinant of the square matrix \fVX\fR.
.LP
For polynomial matrix \fVdet(X)\fR is equivalent to \fVdeterm(X)\fR.
.LP
For rational matrices \fVdet(X)\fR is equivalent to \fVdetr(X)\fR.
.SH EXAMPLE
.nf
x=poly(0,'x');
det([x,1+x;2-x,x^2])
w=ssrand(2,2,4);roots(det(systmat(w))),trzeros(w) //zeros of linear system
A=rand(3,3);
det(A), prod(spec(A))
