## Description

1. Creating Scalar Variables Create the following variables. Each construction should be done

in one line. Make sure to use the assigned variable names.

(a) a =

5.7π

6.9

(b) b = 239 + e

5 − 2.5 × 1023

(c) c = ln(4.23) × sin−1

(0.7)

(d) z = (3 + 2j) × (4 + 5j)

2. Complex Operations Find the real part, imaginary part, magnitude, phase and complex

conjugate of z calculated in question 1e.

3. Vector and Matrix Variables Create the following variables. Make sure to use the assigned

variable names. When doing part c and d, make sure you know when to use the colon operator : ,

and when to use linspace.

(a) Create a row vector where aV ec =

3.14 15 9 26 + 0.1j

, and generate matrices A1 and A2

with repmat and concatenation respectively, where

A1 = A2 =

3.14 15 9 26 + 0.1j

3.14 15 9 26 + 0.1j

3.14 15 9 26 + 0.1j

(b) Create the column version of aV ec, with both matrix constructor operation [ ] and transpose

function in MATLAB. Name the variables bV ec1 and bV ec2 respectively.

(c) Create a row Vector cV ec where the numbers ranges from -5 to 5 in increasing order and at an

interval of 0.1 between consecutive numbers.

(d) Create a column vector dV ec where there are 100 evenly spaced points between -5 and 5. Do

not use the same operator in part c. Optional : Can you do it in one line?

(e) Create a matrix B where B =

1 + 2j 10−5

e

j2π 3 + 4j

(f) Use eye to ATTEMPT to create a 1, 000, 000 × 1, 000, 000 identity matrix.
