Matlab Assignment #1

PART 1:The following problems make use of Matlab in "interactive mode" . You should find it similar to working on your calculator, but with a more convenient interface and nicer plots!

READING: Ch.1, Ch. 2, and Ch. 5 sections 1 &2 in your Matlab book

SUBMISSION: Create a diary which shows the following computations being performed. Submit a printed copy of the diary by 3/4/99.

COMPLEX NUMBERS:

Perform the following computations using Matlab:

1.) (6+j4)+(9+j3) 3.) (7-j3)(j5)

2.) (6+j4)(9+j3) 4.) 9(2+j6)/(1+j4)

MATRIX ALGEBRA:

Repeat problems 8.9, 8.15 a & b, and 8.23 from your EXCEL textbook using Matlab.

(You did all of those problem in Excel assignment #3).

Solve the following system using Matlab:

(2+j3)x + 4y + 5z = 10

3x + (4+j5)y +2z = 18

9x +7y + (8-j6)z = 23

PART 2: The following exercises use the scripting capability of Matlab. You will write some simple m-files using sequential I/O and assignment statements.

READING: Ch. 3, Sections 1-3 in your Matlab book.

SUBMISSION: Submit a printout of your m-file and a diary showing its use by 3/4/99.

Create a script that reads 3 input values from the user, and displays the sum, product, and the sum of the squares of all 3 numbers. Your output should have the following format

Sum is: x.xxxe+yy Product is: x.xxxxe+yy

Sum of Squares is: x.xxe+yy
