Matlab question
Task 2 It turns out that some values in lab4_plot_data.txt vary too much from the sin(x) curve and should be removed as they are considered noisy (invalid). You are tasked with the following: a) Remove the noisy data using the following rules. Do not set the invalid data points to 0, 1) or NaNl Use logical statements in addition to true (1) and false (O) values to complete the task. a. An absolute difference of 0.4 or greater between the data point and the sin(x) value is deemed noisy b. The 11"), 591 and 88"data points are also deemed noisy. b) Plot the valid (noiseless) data points as blue circles on the same figure produced in Task 1. Therefore, the red circles now represent the noisy data while the blue circles represent the valid data. Remember to include a legend.
