Exercise 1: Build a VI that reverses the order of an array that contains 100 random numbers. For example, array[0] becomes array[99], array[1] becomes array[98], and so on. tip: Use the Reverse 1D Array function located on the Functions>>All Functions>>Array palette to reverse the array order. Save the VI as Reverse Random [login to view URL] in the C:Basics I directory. Exercise 2: Build a VI that generates a 2D array of three rows by 10 columns that contains random numbers. After generating the array, index each row, and plot each row on its own graph. The front panel should contain three graphs. Save the VI as Extract 2D [login to view URL] in the C:Basics I directory. Exercise 3: Build a VI that displays two plots, a random plot and a running average of the last four points, on a waveform chart in sweep update mode. Use the following tips: • Use a For Loop (n = 200) instead of a While Loop. • Use a shift register with three left terminals to average the last four data points. • Use the Random Number (0-1) function located on the Functions>>Arithmetic & Comparison>>Express Numeric palette to generate the data. • Use the Bundle function located on the Functions>>All Functions>>Cluster palette to group the random data with the averaged data before plotting. Save the VI as Random [login to view URL] in the C:Basics I directory.
