A task that requires multiple outputs in a specific order.

As a basic level MATLAB user, I could not solve the following problem despite several attempts. Could someone please suggest on how to solve this:

Write a function called corners that takes a matrix as an input argument and returns four outputs: the elements at its four corners in this order: top_left, top_right, bottom_left and bottom_right. Solve without using loops and if-statements.

See an example run below:

>> [a, b, c, d] = corners ([ 1 2; 3 4])

a =

1

b =

2

c =

3

d =

4

Answer 1

[David Fletcher]

function [a, b, c, d] = corners(matrix)
    a=matrix(1,1);
    b=matrix(1,end);
    c=matrix(end,1);
    d=matrix(end,end);
end

It's worth going through the Matlab Onramp course to get an idea of basic indexing - this is fundamental to understanding how to use Matlab

Thanks alot! I'll check out the Matlab Onramp course as well.
