Error when I try to use Code Analyzer suggestions

I get the following warning: INV is slow and inaccurate. Use A\b for INV(A)*b , and b/A for b*INV(A)
the warning happens at at these 3 lines
a = a1 + p1*Z'*inv(f1)*(vt);
p = p1 - p1*Z'*inv(f)*Z*p1;
s(t,:) = v'*inv(f)*v;
I have tried to follow the suggestion without success. Probably I haven't understand the right equivalent syntax.
How I should write these code lines?

thanks, I know that it's only a warning not an error, the error happened in calculation because I have made a mistake in the attempt to follow the hint.
