Question 2 Problem Definition Write a MATLAB script that uses nested loops to create a 100 by 100 element 2D array representing an image that shades from white at the top to black at the bottom. Your script should save the image in a file called test2.png.

Answer 1

Question 2:

CODE :

a = uint8(zeros(100,100)); %UINT8 Convert to unsigned 8-bit integer.
int = floor(linspace(255,0,100)); % generate 100 level form 255 (white) to 0 (black)
for i=1:100
for j=1:100
a(i,j)=int(i); % i choose the row number
end
end
imshow(a) % display image
imwrite(a,'test2.png'); % to write image

Result:

a -uint8(zeros (100, 100)); int for i-l:100 %UINT8 Convert to unsigned 8-bit integer floor (linspace(255, 0,100)); % generate 100 level form 255 (white) to 0 (black) for j-1:100 end 2- a(i,j)-int(1); % 1 choose the row number 7 8- imshow(a) % display image 9-1mwrite (a,' test2.png'); % to write image end Command Window New to MATLAB?

Question 3:

CODE :

a = uint8(zeros(100,100)); %UINT8 Convert to unsigned 8-bit integer.
int = floor(linspace(0,255,100)); % generate 100 level form 0 (black) to 255 (white)
for i=1:100
for j=1:100
a(i,j)=int(j); % i choose the row number
end
end
imshow(a) % display image
imwrite(a,'test3.png'); % to write image

Result:

uint8(zeros (100,100)); %UINT8 Convert to unsigned 8-bit integer. a int -floor(Linspace(0,255,100)); % generate 100 level form 0 (black) to 255 (white) for i-1:100 = 2- for j 1:100 a(i,j) int (j); % i choose the row number end 7- 8- 9- end inshow (a) % display image imwrite (a, 'test3.png'); % to write image Command Window New to MATLAB?

Question 4:

CODE :

a = uint8(zeros(100,100)); %UINT8 Convert to unsigned 8-bit integer.
int = floor(linspace(255,0,100)); % generate 100 level form 255 (white) to 0 (black)
for i=1:100
for j=1:100
a(i,j)=int(j); % i choose the row number
end
end
imshow(a) % display image
imwrite(a,'test4.png'); % to write image

Result:

-unt8(zeros (100, 100)); %UINT8 Convert to unsigned 8-bit Integer. a int for 2- -floor (linspace (255,0,100)); % generate 100 level form 255 (white) to 0 (black) i-1:100 for j 1:100 end a(1+))-int (j); % 1 choose the row number 7 8- 9- end imshow (a) % display image imwrite (a,' test4.png' ); % to write image Command Window New to MATLAB?
