Guys .. I am new to MATLAB

trying to plot bode's plot ...

MagH=16564.3*sqrt(w.^2+7574620^2)./sqrt(w.^2+836.738^2).*sqrt(w.^2+1346260^2).*sqrt(w^2+66497800^2);

I have set of poles and zeros with DC gain .. , the error message I am getting is

Error using ==> mpower
Matrix must be square.

not sure what does Matrix must be square means ..

any help is much appreciated ...
 

Matlab by default deals with matrices. When you include ^2, it means matrix squaring which can be performed only for a square matrix. As you are dealing with vectors, use .^2 as you have done for all multiplications and divisions. Just the last w^2 is wrong here.
BTW a better way to plot bode would be to use tf and use bode command.
