[MATLAB] Adjusting subplot size

These two article in StackOverflow mentioned that :

How to adjust the picture size and position???

1. How can I set subplot size in MATLAB figure?

2. How do I position subplots in MATLAB?

But there is one thing we need to notice, not to use "i" or "j" as variable index.

Because in matlab, "i" or "j" might be seen as imaginary number of complex number.

( i or j = sqrt(-1) , ie. complex number c = a + bj or c = a+bi, a is real number part and b is imaginary part)

I hope it helps!
