Rounded input of a chemical plant

A chemical plant has an input of $10$ different materials per day for daily operation. Each input material weighs more than $1$ ton and doesn't exceed $100$ tons. At the end of the day the weight of all the input materials are added and rounded up for general bookkeeping on material consumption.

Write a function called MaterialSum$()$ that takes a row array with the weights of $10$ materials, calculates the sum of the weights, and then returns the sum. Then, output the returned sum to two decimal places.

Ex: Given:

Output:

The daily sum of all the materials is $513\mathrm{.}66$ tons

$1$ function dailyMaterialsum $=$ Materialsum $($weightArray$)$

$\%$ Write a function that sums the elements of the weightarray

$\%$ and prints the result to $2$ decimal points

dailyMaterialSum $=$ round $($MaterialSum$,2)$

end

Code to call your function $0$

$1$ The weight of each material is in tons and is between $1$ and $100$ tons.

$\%$ You can generate $N$ random numbers in the interval $(a,b)$ with the formula

$\%r=a+(b-a)***rand(N,1).$

weightArray $=(1+(100-1)**($ rand $(10,1)){)}^{\text{'}}$

dailyMaterialSum $=$ MaterialSum$($weightArray$)$
