Question

USING MATLAB

Create a grayscale art image 1000px x 1000px using MATLAB. You must implement the use of grey scale. Be creative. You can earn up to 5 additional points.

Answer #1

1)

%-------------The program is to fade the image as it move from left
corner

%to right corner of the image. Left corner has 0 grayscale
value(black) and right

%corner has 1 gray scale value(white)

clc

clear all

close all

size=1000;

pic=[];

p=0;q=0;

for m=1:size

for n=1:size

pic(m,n)=sqrt(((m/1000-p)^2+(n/1000-q)^2)/2);

end

end

imshow(pic)

2)

clc

clear all

close all

pic=magic(1000); %It creates a magic square matrix with the range
of 1 to 2^n

imagesc(pic) %Scales the image data to the full range of current
colormap

colormap(gray(256)) % set the color to gray scale range of 0 to
255

axis equal %Equal axis in both x and y direction

Using MATLAB:
1) Create three variables to hold the amplitude, phase shift,
and number of cycles for your sinusoid.
2) Create a sinusoid that has 100,000 points with the amplitude,
phase shift, and number of cycles specified in the variables.
3) Generate three test sinusoids:
Amplitude = 5, Phase = pi/2, cycles = 5
Amplitude = 0.7, Phase = 0, cycles = 10
Amplitude = 8, Phase = -2pi/3, cycles = 4
Can someone help me with the exact formula...

Matlab
Create plot of the following density functions using x values
between -10 and 10 with an increment of 0.02
-Normal cumulative distribution function with mu=1, sigma=1,
mu=0, sigma=2, mu=0,sigma=1/2

USING MATLAB
Create a series of if/elseif statements that check which coin
is entered, and sets the variable value to be the correct value of
the coin. The following are the cases to consider:
If coin equals ‘q’, then value equals 25
If coin equals ‘d’, then value equals 10
If coin equals ‘n’, then value equals 5
If coin equals ‘p’, then value equals 1
Otherwise, if the coin is none of the above, add a default else
statement...

Using Matlab:
Generate a random signal ‘x’ with a length of 8000 and sampling
rate of 8kHz. Plot a section of the signal In the time domain. Is
it possible to observe significant trends in the time domain
signal?
Plot the magnitude of the DFT of segments of ‘x’ of different
lengths. Use a decibel scale for the vertical axis. What do you
observe as the segment length increases? Use the Matlab function
‘periodogram’ to obtain...

Using Matlab, evaluate ? = (? + 10) (?^5 + 1) for values of x in
the range of -1 to 1 in step sizes of 0.1.
Hence, plot y versus x.
Could you also include the Matlab code and the associated
screenshots?

For this problem, you must create a table of values for x in
[−1, 1] with a separation of h = 0.02 for the function f(x) = x5 −
0.36x3 + .2563. Then create the table for the approximate f′(x), as
in the example problem. Make sure to format the cells as Number so
values appear correctly. For the cells in columns B and C, use
decimal numbers with 6 places. Once the table is created, make the
scatterplot that...

Create a list of three (3) recommendations that you
believe One Pharmacy needs to implement to avoid any further
complaints from your customers. Your recommendations must include
the use of business technology and/or online services. Remember,
your resources and budget are very tight, therefore your
recommendations need to include practical strategies that do not
require a great deal of money or additional resources. Refer to the
One Pharmacy policies and procedures provided in your handouts to
assist you.

MATLAB
Create an M-File for this IVP,
dy/dt =
t^2 - 16*sin(t), y(0) = 0 and create an anonymous function
g so that it evaluates the slope field at points of our new
ODE.
Ensure you use commands of using a for loop to plot the exact
solution for the IVP in this exercise as well as the Euler
approximations for Δt=0.5, Δt=0.25, and Δt=0.125 all on the same
graph.

Use Matlab to solve the following
(a) Create a plot with a sphere at the center of the graph
(origin) representing the sun with a radius of 6955000 km. Make
sure that the outside of the sphere is painted in ’autumn’ colors.
(Hint: look up the sphere() function, the colormap() function, and
the surf() function).
(b) Create a variable t ranging from 0 to 2? with increments of
0.01.
(c) The following Table gives you important values needed to
compute...
