MATLAB MODULE 1
1. Compare MATLAB with other high level language
Answer
Comparison: MATLAB Scripts & BASIC
There are many similarities between the language used for Matlab scripts and more
the more familiar BASIC programming language (and other higher level languages
such as FORTRAN PASCAL or C.
This document may help when becoming familiar with Matlab scripts.

Variable Assignments
In Matlab, all variable assignments are case sensitive, so the variable Test1 is different from the
variable test1. In Matlab, if an assignment is terminated with a semicolon, Matlab does not
print out the result. If it is not terminated by a semicolon, it will print out the results of the
assignment (In the Matlab code below, there is no semicolon after the assignment for A. This
causes Matlab to print the answer).
R = 2
P = 3.14
A = P*R^2
PRINT A
12.56
R = 2;
P = 3.14;
A = P*R^2
ans =
12.560
Printing
PRINT "Area = ";A;" m^2" disp(['Area = ' num2str(A) ' m^2']);

Conditional Execution
The code below shows a simple set of Block-If statements. In some older versions of BASIC,
there is no Block-If structure and so it would have to be done strictly using GOTO statements.

if Sel = 1 then
print "Selection is 1"
elseif Sel = 2 then
print "Option 2 Here"
else
print "None of the Above
endif
if Sel == 1
disp('Selection is 1');
elseif Sel == 2
disp('Option 2 Here');
else
disp('None of the Above');

Prompting for Input
The following code will prompt for a value from 1 to 10. This also demonstrates the use of
a WHILE in Matlab to wait for a valid input
15 Print "Pick Number between 1 &
10"
Input V
if V<1 or V>10 then 15
V = 0; % Initialize to value<1
% so it does the loop at least once
while V<1 | V>10
V = input('Pick Number between 1 & 10
');
end
Loop Structures
The code below is a simple example of a FOR loop which prints the sum of the squares of the
sines of all angles from 0 to pi/2 in increments of 0.001
SumTh = 0
For Theta=0 To 3.14 Step 0.001
SumTh = SumTh + sin(Theta)^2
Next
Print "Sum is ";SumTh
SumTh = 0;
for Theta=0 : 0.001 : 3.14;
SumTh = SumTh + sin(Theta)^2;
end
disp(['Sum is ' num2str(SumTh)]);
Because of the vector nature of Matlab, it is often possible to replace a FOR loop with an array
process. The code below creates an array called Theta which contains all of the angles. It then
calculates the sines of all of the values in one statement. This script runs about 10 times faster
than the previous code. (This is unimportant for a short script, but for a script which takes several
seconds or longer, this can be significant.) Note the use of the array operator. ^ to square the
array of sines. This is required since the operation sTheta^2 would perform the matrix
multiplication sTheta*sTheta, and would result in an error since sTheta is not a square matrix.
Theta=[0 : 0.01 : 3.14];
sTheta = sin(Theta);
SumTh = sum(sTheta.^2);
disp(['Sum is ' num2str(SumTh)]);

* * * * * * * BASIC * * * * * * * * * * * * * * MATLAB * * * * * * *
There are many matrix functions in Matlab that are not available at all in BASIC.
Some of the more useful ones are shown below.
COMMAND What it Does
x =
zeros(100,2); Makes x a 100 row by 2 column matrix with all zeros
y =
ones(20,20); Makes y a 20 row by 20 column matrix with all ones
z = 0:.1:10; Puts the values of 0,.1,.2,...10 into the variable z
a = z.^2;
The .^2 operator will take each individual element of z and square it,
so a will contain 0,.01,.04,...100
b = a.*z;
The .* operator will take each individual element of a and multiply it by the
same element in z. The equivalent code in BASIC would be
for i=1 to 101
b(i) = a(i)*z(i)
next i
C = rand(3,3);
D = ones(3,3);
E = C*D;
The first command makes C a 3-by-3 matrix of random numbers between 0
and 1. Matrix D will be all ones, and the matrix E will be the matrix product of
these two matrices (so each element of the top row of E will be the sum of the
first row of C.
2. Write a note on applications of MATLAB.
Answer
MATLAB can be used in the following Fields:
*Computations including linear algebra, data analysis, signal processing,
polynomials and interpolation, numerical integration, and numerical solution of
differential equations.
*Graphics, in 2-D and 3-D, including color, lighting, and animation.
MATLAB (matrix laboratory) is a numerical computing environment and fourth-
generation programming language. Developed by Math works MATLAB
allows matrix manipulations, plotting of functions and data, implementation
of algorithms, creation of user interfaces, and interfacing with programs written in
other languages, including C, C++, Java, and Fortran.

Although MATLAB is intended primarily for numerical computing, an optional
toolbox uses the MuPAD symbolic engine, allowing access to symbolic
computing capabilities. An additional package, Simulink, adds graphical multi-
domain simulation and Model-Based Design for dynamic and embedded systems.

entries are those in the array b each replicated m-times. Write
MATLAB function d = repel(b, m) that generates array d as

and returns an array d whose each entry is taken from the array b
and is duplicated according to the corresponding value in the array
m. For instance, if b = [ 1 2] and m = [2 3], then d = [1 1 2 2 2].

3. Write a script to load the data file randomData.mat (which contains variables x
and y) and fit first, second, third, fourth, and fifth degree polynomials to it. Plot the
data as blue dots on a figure, and plot all five polynomial fits using lines of
different colors on the same axes. Label the figure appropriately.
Hint: To get good fits, you’ll have to use the centering and scaling version of
polyfit (the one that returns three arguments, see help) and its counterpart in
polyval (the one that accepts the centering and scaling parameters).
