Explanation / Answer

%1x3 vector
vec13 = (1:3)
%3x1 vector; ' transposes a vector
vec31 = (1:3)'

%linspace(a,b,c) creates a vector of c elements evenly spaced between a,b
x = linspace(2,100,50)

%each till each semicolon will be a row
vec22 = [1 2;3 4]

%use abs(x) to get the absolute value of -134
abs(-134)
