# 1. Image manipulation

• Create a 10x10 matrix that contains any number from 1 through 10 at least once. The numbers may be in any order. Create the matrix using a double for loop.
• Create a colormap matrix such that each number is mapped to a unique color.
• Use the image command to plot your image.
• Use the colorbar command to show a colorbar.
• Describe (in words) how you could change the colormap matrix to achieve the same result.

# 2. Using  fill  or  image

Write a MATLAB code that draws 8-by-8 checkerboard with red and black tiles.

# 3. Color map and images

Write a Matlab script to create an image as follows: ( Note: you need to provide seven colors and the correct orientation of the strips.)

# 4. Create images

Run the following Matlab code.

clear;
i=0:2*pi/1000:2*pi;
x=sin(i);
y=cos(i);
fill (x,y, 'r', 'EdgeColor', 'r');
hold on
fill (x*0.98, y*0.98, 'b', 'EdgeColor', 'b');
hold off
axis equal off

# 5. Plots

(a) Plot the following equations, first by choosing points within the range as a vector, computing the associated y values, and finally by building a proper plot using MATLAB statements.

0 < x < 4π, $y = \frac{1}{16} sin (x^4) - \frac{1}{8} cos(x^3) + \frac{1}{4} sin(x^2)-\frac{1}{2}cos(x)$
