Problem 1. Create a vector representing x coordinates of a measurement with 20 points between 0 and 10. Create another vector y representing fake measurements which are related to the above x values as y = 2.3 x - 1.2. Next add random (normal, Gaussian) noise to the vector y. Plot on the same graph both versions of vector y in different colors. Next use attached linregr.m function to find a least square fit (linear regression) for your fake experimental data.
Problem 2. Create a three dimensional diagram of function z = (x-2)2 + (y-3)3.

Write a program that reads in numbers (of type double) from a file, stores them in an array, and then calculates the mean, variance, and standard deviation. Your program shoul
The secant method is an iterative root nding method that is super-linear. The method has the advantage that it is faster than linear methods and does not require knowledge of the
Linspace function: Likewise, the linspace function generates a linearly spaced vector; linspace(x,y,n) generates a vector with n values in the inclusive range from x to y. For
