c++ - Is it bad practice to implement a graph's nodes as a vector of pointers? -

-

i attempting implement graph in c++ each node instance of class a. first instinct represent collection of nodes in graph object vector of objects of type a.

however, wanted implement following functionality well: suppose overload + operator when g_2 = g_0 + g_1 (where g's instances of graph class), g_2's nodes consist of combined nodes of g_0 , g_1. if modify of nodes in g_2, g_0 , g_1's nodes remain unchanged , in sense g_2 no longer remain sum of g_0 , g_1. however, if instead represent nodes in graph vector of pointers objects of type a, modifying g_2 modify g_0 , g_1, , vice versa, desirable project working on.

that being said, can't suspect having vector of pointers data member dangerous, don't know enough say.

a vector of pointers fine. need take care of memory management of objects yourself, doable.

you need allocate objects new a() , delete them delete pointer_to_a if want rid of them.

i'm trying code cyclic autocorrelation function in matlab follows: t=0:(n-1); t=t*te; i_alpha=0; tau=-n2*te:te:n2*te; alpha=-1/2:1/n:1/2; ryy_cl=zeros(length(alpha),length(tau)); alpha=alpha/te ind_tau=0; i_alpha=i_alpha+1; k=tau ind_tau=ind_tau+1; if k>0 % ryy_cl(i_alpha,ind_tau)=1/length(sig_bin_syl_mod(1:end- k))*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(1i*2*pi*alpha*t(1+k:length(sig_bin_syl_mod(1:end)))); ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(-1i*2*pi*alpha*t(1:end-k)); else ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1-k:end)).*sig_bin_syl_mod(1:end+k)).*exp(-1i*2*pi*alpha*t(1-k:end)); end end end i'm getting errors, , doesn't show expecting. according below formulae, how can fix it? the code provided incomplete, difficult confidently reproduce error. in particular, haven't de...
