Write a MATLAB function that will generate chi-square random variables with v degrees of freedom by generating v standard normal, squaring them and then adding them up. This uses the fact that is chi-square with v degrees of freedom. Generate some random variables and plot in a histogram. The degrees of freedom should be an input argument set by the user.

You are using a poorly constructed 4-bit natural binary-coded absolute encoder and observe that, as the encoder rotates through the single step from code 3 to code 4, the encoder outputs several different and erroneous values. If misalignment between the photosensors and the code disk is the problem, what possible codes could result during the code 3-to-4 transition?

Using energia software
Write a program for your MSP430 board to will perform the following three tasks: 1. Input: Take a character string as user input through the serial interface. 2. Processing: Convert the entire string to lower case, and 3. Output: Return the processed string to serial output, which will be displayed on your computer monitor. Example: If the input character string is, “Here I am”, the output should be, “here i am”. For serial input and output purpose, you should use the serial monitor feature of the Energia. Note: After completing your homework, make a video of your work with verbal explanations. Make sure your face is seen in the video. If your LaunchPad or Serial Monitor is not responsive when the TA comes to check your homework, show the TA your video.

Part 1. MATLAB Programming The wind chill
factor measures how cold it feels with a given air temperature T
(in degrees Fahrenheit) and wind speed (V, in miles per hour). The
formula is approximately
WCF = 35.7 + 0.6T ? 35.7(V0.16) + 0.43T(V0.16)
a). Write a function that will calculate the wind chill factor
(WCF) given temperature and wind speed. Your function should round
down to the nearest integer.
b). Write a script that will use the function above to create a
table of wind chill factors, similar to the one shown at
https://en.wikipedia.org/wiki/Wind_chill#/media/File:Wind_chill.png.
Wind speed should be down the left and temperature across the
top.
Please show output if possible Thanks
