Introduction to Maple
Maple
Maple is computer algebra software
Great for symbolic computations
MATLAB is for numerical calculations
Originally developed at the University of
W
Programming in MATLAB
Powerful, yet simple programming language
Very little syntax
Many built-in functions
Saves you having to code your own
Can be slow, in some cases
Able to do matrix manipul

Vector Operations in MATLAB
Vector Operations in MATLAB
Use square brackets to denote a vector: [ ]
For row vectors, use a space or comma
between elements
a = [1,2,3] or a = [1

Linear Systems & MATLAB
Linear Systems
Many problems in engineering can be
approximated by linear relationships
For linear systems, solutions to problems are
often easy

Small Samples
Small samples are those with n< 30 elements
Our z-statistics are no longer accurate
Must use t-statistics

Standard Error
The standard deviation of the means is called
the standard error
Describes the variation of the means about the
estimated mean
We usually do not know the true standard
