how to connect matlab and openCV

i have searched alot on internet and tried those things too, but i'm not able to connect matlab with opencv.. i want to do it so that i can use opencv functions in matlab, for example, i want to write and execute this in .m file in matlab:

i=imread('my life.jpd');

cv.imshow(i);

how to do it? can someone let me know the detailed procedure? is there any direct way to do it? because i've followed alot of tutorials for doing this thing, but following all those, the end result was same, i was unable to do it :(
