Matrix Algebra and Chemometrics Using MatLab
... 11. Remember those complicated least squares equations you used in Program #5? They are equivalent to the matrix solution to the problem, and of course using matrices is so much easier! Here's how to do it. We have a data matrix Y, which consists of a single row: Y = [y1 y2 y3 ....yn] For example, t ...

... 2. For an equation, if all the even powers of x have same sign coefficients and all the odd powers of x have the opposite sign coefficients, then it has no negative roots. 3. For an equation f(x)=0 , the maximum number of positive roots it can have is the number of sign changes in f(x) ; and the max ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
