Question

7) Use MATLAB to create a pattern such as the one below in the command window. Prompt the user to enter the max number of columns and number of intervals ran. In the left figure, the user selected 10 max columns and one interval. In the right figure, the user selected 5 max columns and two intervals. The program should run for n max columns and n number of intervals. ******* ** **** *** ***** ******* ***** ***

Answer 1

c = input("Number of columns to print : ") % Taking user input
n = input("Number of intervals to print : ")

while (n>0) % while loop to repeat number of intervals

for i = c:-1:1 % for loop to print first half of the pattern
     for j = 1:i
        fprintf('*')
     end
     fprintf('\n')
end

for i = 2:c % for loop to print second half of the pattern
     for j = 1:i
        fprintf('*')
     end
     fprintf('\n')
end

n = n-1 ; % decreasing interval count for evary iteration

end

c = input("Number of columns to print : ") % Taking user input in = input("Number of intervals to print: ") while (n>0) % while loop to repeat number of intervals for i= c.-1.1 % for loop to print first half of the pattern for j = 1:1 fprintf("*') end fprintf("\n') end for i = 2:0 % for loop to print second half of the pattern for j = 1:1 fprintf(**) end fprintf("\n') end n=n-1;% decreasing interval count for evary iteration end
