Question about length function

array1 = [1 4 7 3 5 8 9; 12 13 11 10 14 19 17; 22 29 21 24 27 28 20; 33 31 39 30 38 34 35; 41 42 45 49 48 47 46];

The question is

How can you obtain the number of rows and the number of columns of a matrix by applying the length function?

I think the length function shows only the longest length of matrix, so I do not know how to make commands.

[rows,columns] = size(array)

Maybe I did not understand the question, but shouldn't I use only length function to show ros and columns?

Hint: Use indexing for row and column separately.

[SeungHyun Cha]

length(array1(:,1))

ans =

     5

length(array1(1,:))

ans =

     7

Thanks...!

Exactly! Now make it as a function that returns two outputs.
