Plot a function (approximation of pi) in MATLAB

matlab least squares approximation in this activity you will use least squares approximation t0 find curve of best fit for data set consider the four points in the plane 23 1 1 0 and 2 1 use 31412

SOLVED: Problem 1(submit online) Write a function in MATLAB to simulate an 8-bit successive approximation process.Your function must be named exactly as shown in Figure 1.Input parameters value and reference represent the sampled input voltage and reference voltage, respectively. Output result should be an 8-bit binary number represented as a string (i.e., 123 =01111011'). Submit your MATLAB function separately to CANVAS in m-file format (A2D.m). function result]-A2Dyalue,reference UNtiTLED summ
