Function returns mapping to another function variable

Questions:

1. When i have 2 returns in the below function why does the "ans" only shows the value of "c" and not "d" or "absx" or "absy" ?

function [absx,absy] = my_first_function1()

input = 3;

b = [1 2 4; 3 4 6; 4 2 3];

c = input*b;

d = inv(c);

absx = c;

absy = d;

c

d

end

>> my_first_function1

c =

3 6 12

9 12 18

12 6 9

d =

-0.0000 -0.0667 0.1333

-0.5000 0.4333 -0.2000

0.3333 -0.2000 0.0667

ans =

3 6 12

9 12 18

12 6 9

2. How can i use the "absx" and "absy" inside another function.

My intention is to map x to absx and y to absy

function my_first_subfunction1()

my_first_function1

x = absx

y = absy

disp('..........')

z = x;

z

w = y;

w

end

If i use the above code it tends to throw an error like

Unrecognized function or variable 'absx'.

Error in my_first_subfunction (line 3)

x = absx

1. "ans" shows the value of "absx" because that is the first output argument from the function my_first_function1. To suppress "ans" showing on the command line, terminate the call to my_first_function1 with a semicolon, like this:

my_first_function1();

2. In order to use "absx" and "absy" somewhere else, you have to assign their values to variables in the caller workspace (i.e., use the output arguments that my_first_function1 returns):

function my_first_subfunction1()

[absx,absy] = my_first_function1();
% do what you want to do with absx and absy ...

% (note that they don't have to be called absx and absy here, you could do this just as well:
% [x,y] = my_first_function1();
% and then do what you want with x and y.)

end
