Octave/Matlab: How do I read a directory and look for the .csv extensions and then plot the contents? Each of the files have 2 lines I must skip and any other lines that contains characters. I want to plot the first column against the third column.

Need another function written in python from the csv link

4. Fast in java coding please. Thank you File Encryption is the science of writing contents of a file in a secret code. Yourencryption program should work like a filter, reading the content of one file,modifying the data into a code, and then writing the coded contents out to a secondfile. The second file will be a version of the first file, but written in secretcode. Write a program to demonstrate the above working with binary files.

A miniature robot designed to mimic the behavior of an ant is being tested to evaluate the robot’s ability to avoid a chemical repellant (the robot has a chemical sensor, and a control loop that makes the robot avoid moving in a direction that will result in the sensor detecting a chemical concentration above a certain limit). The x and y positions of the robot are measured with time, and the resulting data is saved to a file called data.txt which contains 3 columns: the time of the measurement (in seconds), the x position (in cm), and the y position (in cm). The first line of the file is a “header”: it has a single integer that specifies how many lines of data follow. Write a C++ program called ant.cpp that reads files of this type (i.e., your program should work with another, but similar, file!) and then does the following: it asks for an X and Y position, and then prints to screen the time at which the ant robot was closest to this position. For example, if we wish to know when the…

Create a new file cart.html You must get and set the data on the web page by using document.getElementById( ). Each HTML element on the web page already has an id so it is easy. No need for a loop to go through the list of products, there is only 2 products and the info is hard coded on the web page. You must write the code for function cartTotal().

Your professor asked your TA to collect student information and store it in a file called studentInfo.txt, but this TA spilled Pepsi on the keyboard while entering the data. As a result, there are extra or missing spaces and missing commas throughout the file. For example, the file has wd50,WillDavidson, 090,3 hpj4332, Helen Jordan1983.88 xd222XavierDavies1983.65 ad12 AdDavies1983.65 Suppose the file contains netID, name, major, and GPA in that order. Can you help this TA make the file more readable? To accomplish this task, you may assume the following about each field: netID: begins with 2-3 lowercase letters followed by 1-4 digits (e.g., wd1, wxo001, tsy1234) name: contains both first name and last name with their first letter capitalized (e.g., "John Doe", "MarySmith"). There may be zero or more spaces between the first name and last name. major: 3-digit code (e.g., 198) GPA: floating point number between 0.0 and 4.0 (inclusive). There may or may not be a decimal point (e.g., 3.0…
