In this problem you can use the function min. Suppose that we want to find the minimum of a

function $f(x),$ with xin$[a,b].$

$($a$)$ Write a MATL $B$ function, called minBasic.m$,$ that takes a and $b$ as input and returns

the minimum value of the function $f(x)=x^2.$ Also write how you would call the function

at the command prompt.

$($b$)$ Write a M $$ TL $B$ function, called minFunction.m$,$ that would return the minimum value

for any function $f(x)$ defined at the prompt. Also write how you would call the function

at the command prompt in the case where the function you want to find the minimum of

is $f(x)=sin(x).$
