Vectors matrix problem
Say we are given a matrix:
A =
(1 3)
(1 0)
(2 1)
How do we find the set of vectors that are in the row space of A?
Do we do this by row reducing the following matrix?

(1 0 | 0)

Performance analysis of RGBW CFA
Bayer filter mosaic has been used in digital cameras as color filter array (CFA) for more than three decades now. The original reason behind using R:G:B in the ratio 1:2:1 in the CFA was that human

Series convergence
Show that $\sum_{n=0}^{\infty} \frac{(z+i)^n}{2^n}$ converges for all values of z in the disk D(-1)={z:abs(z+i)<2} and diverges if abs(z+i)>2.
abs() means absolute value.
