Write a function $[$fArea$]=$ TrapIntegral$($x$1,$fx$1)$ that accepts $1$D arrays containing a

set of points x$1$ and a set of values fx$1$ calculated or measured at those same points,

and returns the trapezoidal integral fArea$2$ across the entire range of x$1$ values. $($Hint:

there will be one less trapezoid than the number of x$1$ values$)$

$$ Write a script yourBlazerID$\_$IntegralTest.m that generates test arrays x$1$ and fx$1,$

calls your function TrapIntegral, and tests that the output is correct. You can use any

reasonable test strategy, but you have to include comments in your script that clearly

explain your strategy and how your test$($
