EXERCISE $4$

Write a script file that creates a row vector $v$ containing all the powers of $3$ that are $($strictly$)$ less than

${10}^5.$ The output vector should have the form: $v=[3,9,27,81$dots$].$ Use the while loop.

if statement

The basic structure of an if statement is the following:

if condition

$y=\{\begin{array}{cc}{x}^3+2,& x1\\ \frac{1}{x-2},& x>1\end{array}xx=2yx=2y=f(x)x==2x=2^{\text{'}}x1y=x-3+2$;$y=\frac{1}{x-2}$;$xx=-1,x=2x=4f(-1)=f(2)yx=2>f(4)$
