Question
![Given the following piecewise function, f(x):
f(x)= x + 3 when x<-3
f(x)= -2x - 6 when -3 <= x<-2
f(x)= x when -2 <= x < 2
f(x)= -2x + 6 when 2 <= x<3
f(x)= x - 3 when 3 <= x<7
f(x)= -2x + 18 when 7 <= x < 8
f(x)= 2 when x >= 8
Create a function M-file, PieceZigzag, that accepts one or more values as input, evaluates the piecewise function at that number & returns this as output.
The function should accept an array as input for x.
Use a for loop to build the output array containing f(x). Preallocate this array.
Examples:
Piecezigzag(-10)
ans = -7
Piecezigzag( [-10 10])
ans = -7
