min function

dear all,
i m doing following program but it is not working.
where kuufinal and muufinal are mass matrix.
h=[zeros(1,g)]
for i=1:1:g
    x=kuufinal(i,i)/muufinal(i,i)
    x=[zeros(1,(i-1)),x,zeros(1,(g-i))]
    h=h+x
end
H=h
x1=[ones(g,1),zeros(g,(q-1))];
for j=1:1:(q-1)
[c,i]=min(H)
H(i)=inf;
v=[zeros((i-1),1);1;zeros((g-i),1)];
x=[zeros(g,1),zeros(g,(j-1)),v,zeros(g,(g-j))];
x1=x1+x;
end

following error is coming.
??? Undefined function or method 'min' for input arguments of type
'sym'.

Error in ==> Untitled17 at 371
[c,i]=min(H)

plz help to correct.
thanks and regards.

You cannot use the MIN function on symbolic arrays. One reason for this:
what is the minimum value of [sym('x'), sym('y')]? You will need to convert
the symbolic expression into a numeric array (using the DOUBLE function) in
order to use the MIN function.
