.SH NAME
sqrtm - matrix square root
.SH CALLING SEQUENCE
.nf
y=sqrtm(x)
.fi
.SH PARAMETERS
.TP 10
x
: real or complex  square matrix
.SH DESCRIPTION
\fVy=sqrt(x)\fR is the matrix square root of the \fVx\fR x matrix (\fVx=y^2\fR)
Result may not be accurate if \fVx\fR is not symmetric.
.SH EXAMPLE
.nf
x=[0 1;2 4]
w=sqrtm(x); 
norm(w*w-x)
x(1,2)=%i;
w=sqrtm(x);norm(w*w-x,1)
