I need help understing what to do here,
I know i need to slobe for p1 and p2x but stuck, I have the code below but just stuck.
x = 0:0.1:20;
noise =?? % a number, to define
y= 4*x + noise*rand(1,length(x));
Vary the value for noise as 0, 50 and 100 to get three different results for 𝑝1and 𝑝2,
From a linear algebra standpoint, determine the coefficients, 𝑝1and 𝑝2, of the least-squares-regression of a line fit through the data defined above.
