Matlab for Signal Processing-Lesson 02

Suppose we have a matrix M defined as M= [π e^π; 0 -1] and a vector a vector v defined as v = [ 3 4 ] .

Then we suppose we want the vector dot - product (also called the “inner product ” ), and then entering the summation will compute the column sum of the vector. Now suppose we wish to find q= v*v^T . Note that v is a column vector (dimension 2 × 1), and thus q will be a 2 × 2 matrix

Those matrices may be entered into MATLAB using

M = [pi exp(pi); 0 -1]

v= [3 4]

%dot product

p = v.*v

%transpose matrix

M'

We can use conditions such as if-else or switch-case. An example
