How to Retain Graphs in Matlab
 

Using the codes below hopefully I will get 15 graphs, but in fact I only get one. Any function in Matlab can help me retain all of the 15 graphs? Thanks in advance.

for i = 1:15
qqplot(Fkt1(:,i),Student_t15(:,i)) % Display 15 Q-Q plots versus Student-t distribution
end
