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.
Capture the matlab code in a text file.
Find the boundary between each two of the equations P1, P2, P3 by solving: P1 = P2 , P1 = P3 , P2 = P3 Plot the boundary lines on a single figure that also includes the
Input Function: The Input statements read in values from the default or standard input device. In most of the systems, the default input device is the keyboard; therefore the
First order differential equations: Euler's method Finally, we consider ?nding the numerical solution for a ?rst order differential equation given an initial value. We consider
1. Given these sinusoids: x 1 (t) = 0.5cos(25t+20°), x 2 (t)=0.85cos(25t+160°) and x 3 (t)= 0.81cos(25t-145°) (a) Subplot the phasors X 1 , X 2 and X 3 corresponding t
In the manufacturing of ball bearings, the components, such as the ball, are hardened through a process of heating and then rapid cooling or "quenching" by submersion in an oil or
Format command: The format command can be used to control the spacing between the MATLAB command or expression and the outcome; it can be either compact or loose. >> format
