Part 4 - A function to calculate the differences between array items have one item iess thon the input. You must write your function using cither bosic array manipulation or for/while loops - you may NOT use existing MATLAB functions. the number sequence described by out \( -2 x+1 \). This is a perfect example of numerical differentiation. Notice that after calculating the differences, the second-order polynomial \( x^{2} \) is reduced to a first-order (2x \( +1 \) ). https//enwikipediarg/wiki/Numerical_differentiation You are required to do the fallawing: description, where "Test" is the code used to call your function and "Result" is the expected output based on the function call. An example plot is shown below: what quantity do you think we are measuring when differentiating velocity over time - ie what does the value output keep a track af, in this example? Example Plot Example CodeRunner test call For example: Answer: [penalty regime: \( 0 \% \) ]
