Question

Regarding fprintf which of the following is true

Select one:

a.

fprintf is one of the most successful ideas introduced by Matlab and its parent company.

b.

fprintf is a quick and easy way to print matrices if we do not want complicated formatting

c.

fprintf should never be used and will soon be removed from Matlab. The disp command is what one should use

d.

The output of fprintf is strictly machine readable

e.

fprintf is a flexible mechanism to do complicated formatting

Clear my choice

Answer 1

Answer :-

c ).  fprintf should never be used and will soon be removed from matlab. The disp command is what one should use.

i.e.

We use either disp( ) function and fprintf function to display output to the screen.

The disp( ) function is more convenient for displaying vectors, matrices, and complex numbers because disp( ) displays the entire array with a single function call.

Example :-

disp(5)

disp(pi)

disp(3.45)

disp(' hello ') etc.

In comparison with disp( ) fprintf is more complicated to use as it receives more than on arguments.

For every output we have to specify the identifiers with variables.

For example:-

Age = 20;

fprintf('I am %d years old.\n', Age)

fprintf('pi to 10 decimal places = %0.10f.\n', pi)

Etc.

Thumbs up!
