Lectures:
0 - Day 1 Information

1 - Setting up the EAS230 environment on your computer

C++:
2 - Code layout, simple programs - Please read pgs. 1-20 in the text
        a basic C++ program framwork: template.cpp
3 - Variables - Please read all of Chapter 1 in the text.
        a demo of the IF statement: ifDemo.cpp
        a simple menu: menu1.cpp
4 - Ifs and Whiles - including break, continue, and return 0 - Please read Sections 2.2 and 2.3 in the text
    Numerical Methods, calculating an iterative function (extended to summation series): factorial.cpp
5 - Writing our own functions, and using the math.h function library (including the use of BIAS and GAIN) - Please read Sections 3.1 and 3.2 in the text
    Numerical Methods, calculating a best fit equation from known points (extrapolation, line fitting, linear regression): Extrapolation.cpp
    An examples of a function: FunctionExample.cpp
    The sin curve: sin.cpp
Help with Lab 4, an example of using the drawLine function: Draw.cpp
6 - Using advanced function libraries - a simple test of each Library call: Libraries.cpp
7 - Our very own Princeton Egg
    Numerical Methods, statistics using a random number generator (our very own Egg): PrincetonEgg.cpp
    The Global Consciousness Project (video) Princeton Egg Website

8 - Arrays - a simple database: Arrays.cpp
    Please read sections 4.1, 4.2, 4.3 in the text.
9 - Building an iTunes-like database : code here - myTunes.cpp

10 - Bubble Sort
       Numerical Methods, finding the mean, maximum, minimum, and standard deviation of an array in C++.
       Nested for loops: nesting.cpp
       A simple bubble sort of an array of ints into ascending order: bubble.cpp (this program explicitly passes variables via function parenthesis).
An alternate bubble sort program: bubble2.cpp (this program avoids passing variables via function parenthesis by declaring variables outside of main).

Summary of C++ (in single statement format)

Excel:    Get MS-Excel (part of MS-Office) here: Windows Mac

11 - Intro To Excel (and help with Lab 7) - installing and running Excel, entering data and formulas.
        Numerical Methods, columnated data, averages, std dev, min/max, frequency distribution, charting
        Simple Statistics: list.xlsx Sin Curve: sin.xlsx
12 - More Excel - advanced functions and charting
        Numerical Methods, using Excel to find drag, required power, available power, min and max sustainable flight speeds, and max rate of vertical climb of a Boeing 747: flight.xls

MATLAB:

13 - Intro to Using MATLAB - a sample script: Matrices.m
        please read Chapter 8 in the text.
14 - Matrix math
        please read chapters 9 & 10 in the text
        Numerical Methods - solving n equations in n unknowns using a matrix inverse; using matrix multiplication to process tabular data.
15 - N equations in N unknowns
16 - Data Tables - using the min( ) function
17 - Curve Fitting /Smoothing
        please read chapter 11 in the text

Project Assignments:

Lab 1 - a simple program in the JGrasp environment.
Although Lab 1 will not be graded, some future labs will be, and you should practice submitting your lab to UB Learns. Instructions for submitting your lab to UB Learns are here: UBlearns.doc

Lab 2 - this lab is ungraded - a simple calculation using double variable types, cin, and cout. This lab should be completed and comprehended by Friday 9/19.
An exercise to help you get ready fro the first graded lab is posted: Exercise1.pdf . The first graded lab will be posted shortly and will be due Oct. 3.

Lab 3 - due Saturday Oct 4 by 11:59pm. Submit via UB Learns.

Lab 4 - Writing your own functions, FOR loops, and using bias and gain to plot a sine curve - You can use this template to start with: Lab4Template.cpp (but please Save As... to a different filename). Help with Lab 4 - an example of using the drawLine function: Draw.cpp

Lab 5 - a simple blackjack game. This lab is for fun, ungraded. This lab will help you prepare for the midterm. Because this lab is for fun, a solution is provided ( blackjack.cpp ). You should, however, attempt this lab on your own, and work out your own solution.

Lab 6 - working with arrays. This lab will be graded and is due via UB Learns by 11:59:00pm on Saturday, Nov. 1.

Lab 7 - Working with Excel to analyze and chart data. You will need this file: GradesStart.xls. The lab solution is here: GradesFinish.xls

Lab 8 - The objective of this lab is to use UBs virtual computing environment and Microsoft's Remote Desktop Connection to run MATLAB.
Please follow the instructions in the appropriate Powerpoint below -
        If you have a PC: Lab8PC.ppt
          You'll need this (right-click and "Save Link As..."): ubvcl.rdp
            For Windows XP, you might try this: RemoteDesktopForXP
        If you have a Mac: Lab8Mac.ppt
        If you have a Linux computer (also, for the lab computers) - Lab8Linux.ppt
You must -
    1. If off campus, install and run the Cisco AnyConnect Client (if on campus, DO NOT).
    2. Run Microsoft's Remote Desktop Connection (ubvd.rdp if a PC, or a special App if a Mac)
    3. Run MATLAB
    4. Set a local drive destination folder for your MATLAB program (this is very important)
    5. Create and save a MATLAB script.m file.
          Your script file needs only one MATLAB command: A = [ 1 2 3; 4 5 6; 7 8 9 ]

Lab 9 - creating a MATLAB script file.

Lab 10 - working with data in MATLAB, C++, and Excel.
