Question

Use one MATLAB statement to generate each of the following scalars and vectors. (These parts are sequential)

a.) Generate the vector x=(sin5,sin10,sin15,...,sin200) but dont print

b.)Find the Max value in X and which index has this value. Print both the index and the value using Disp (so you can use 2 statements)

c.)Find the minimum value x and which index has this value. Print both the index and the value using Disp (so you can use 2 statements)

d.)Find the difference between the max and min values

e.) find the sum of all the elements of x

f.)find the sum of the absolute value of all the succesive elements of x

g.) find the differences between all the successive elements of x

h.)Find the absolute differences between all the successive elements of x

k.) sort all these elements in increasing order. print this out in two columns. The first containing the values and the second containing the indicies in x where these values occur (so you can use 2 statements.)

l.) Print out the product of all the elements in x, the mean value of these elemnets and their srtandard deviation, and only 1 statement is allowed.

Answer 1

Code in MATLAB :

A = zeros(20,1);

for i=1:20

A(i)= sin(5*i);

end

maximum = max(A);

max_index = find(A == maximum);

disp(maximum);

disp(max_index);

minimum = min(A);

min_index = find(A ==minimum);

disp(minimum);

disp(min_index);

difference = maximum - minimum;

sum_A = sum(A);

absolute_sum_A = (sum(abs(A)));

A_differences = zeros(19,1);

A_abs_differences = zeros(19,1);

for i=1:19

A_abs_differences(i) = abs(A(i+1)-A(i));

   A_differences(i) = (A(i+1)-A(i));

end

A_sorted = sort(A);

A_sorted_index = zeros(20,1);

for i=1:20

A_sorted_index(i) = find(A == A_sorted(i));

end

disp(A_sorted);

disp(A_sorted_index);

product = 1;

for i=1:20

product = product*A(i);

end

mean_value = mean(A);

standard_deviation = std(A);

fprintf('The product is %f \nMean value is %f\nStandard Deviation is %f\n',product,mean_value,standard_deviation);
