How can I make a spectogram out of a wav file

How can I make a spectogram out of a wav file

Well I want to make a spectogram of a song. The first 10 seconds are the
points of my interest. Should I just do this or is it wrong if I am wrong
correct me.
Commands:
song = wavread('C:\Path of My FIle\song.wav')
length(song)/44100
song_seg = lovers(44100*1 : 44100*10)
plot(song_seg) % this command makes my spectogram Hz/Time
