nvalid Pipes $($Vectorized$)$

A machine cuts $N$ pieces of a pipe. After each cut, each piece of pipe is weighed $($grams$)$ and its length $($meters$)$ is measured. These $2$ values are then stored in a file called ME$2004\_$PipeData.mat $($see Canvas$).$ NOTE: In MATLAB Grader, this data file is provided $-$ but you still need to load$()$ it$!$

Invalid Pipes $($Loops$)$

Gravity

The weight is supposed to be between has an invalid weight and$/$or length.

Develop a MATLAB script which returns:

num$\_$invalid, the total number of invalid pipes

invalid$\_$pipes, a row vector storing the indices of invalid pipes

For example, consider the following data:

weight $=\left[\begin{array}{ccc}692& 730& 551\end{array}\right]$;

lngth $=\left[\begin{array}{ccc}1\mathrm{.}23& 1\mathrm{.}17& 1\mathrm{.}38\end{array}\right]$;

Pipe $1$ is invalid because its weight is too low $($despite its length being acceptable$).$

Pipe $2$ is valid.

Pipe $3$ is invalid because both its weight and height violate the boundaries

Thus:

num$\_$invalid $=2$;

invalid$\_$pipes $=\left[\begin{array}{cc}1& 3\end{array}\right]$;

For this problem, you must vectorize! No decision$/$repetition structures! bar$()$ and yline$()$ functions may be useful visualization tools.
