imfuse example is broken

[tanchinluh]

lena.bmp is not in images/, but after conversion of lena.png to lena.bmp
I get this:

--> I1 = imread(fullpath(getIPCVpath() + "/images/lena.bmp"));

--> I2 = imread(fullpath(getIPCVpath() + "/images/lena7030.bmp"));

--> [S,TR,ROT,SC]=imphasecorr(I1,I2);

"Scale Factor = 1"

"Rotation Factor = 0"

"Transition Factor x = 243 y = 202"

--> y = imfuse(I1,S,'colordiff');
at line 37 of function imfuse (
/Users/mottelet/git/IPCV/macros/imfuse.sci line 41 )

Submatrix incorrectly defined.

--> imshow(y);

Undefined variable: y

issue on imphasecorr, will need sometime to relook into this function
