3. Use care when applying goals.
Course Goals
Computer programming skills
Computer as a tool for analysis & display
Collaboration for efficient learning & skill building
Matlab specific knowledge
Goals may cause recurring problems due to narrowed focus and decreased intrinsic motivation.
Use care when applying goals.

4. Scalar Operations & Precedence
( ) parentheses
^ power
/ * \ multiplication & division
+ - addition & subtraction
Precedence Bingo
Mark your 9 squares with numbers
from 1 to 25 (no duplicates)

5. Accounts & Login
Instructor will give each of you a unique login number, it’s the x.
You will be prompted to make a new password (case sensitive).
User: engr-x
Pswd: x
Dom: apptech

6. Variables Case sensitive 32 character max No spaces or math symbols
Avoid command names & predefined constants
sin, exp, size, max, format, help
NaN, pi, Inf, i, j, eps, ans,
= is assignment operator (not the math symbol)
>> VinHtInch = 6* >> y+5=6 syntax error
Name returns the value
>> VinHtCM = 2.54*VinHtInch

7. Error Types Syntax error Logical error
Computer gives red error message
Computer says, “I don’t understand.”
Logical error
Result happens, but is wrong
User says, “That’s not what I meant.”
>> VinHtInch = 6*10 + 6;
>> VinHtCM = 2.54*VinHtinch
??? Undefined function or variable 'VinHtinch'.
