How to create a function with a matrix M as an input

Hello,
I need to write a function with one input argument: a Matrix M. As an output, it should return a matrix that contains only those elements of M that are in odd rows and columns. I understand the idea but its hard to grasp how i will define a matrix M as an input. What I wrote is
function oddmatrix = odd_index(row,col)
M=rand(row,col); temp=M(1:2:end,1:2:end) oddmatrix=temp(:,:)
end
But then M is not an input anymore.
Any help will be highly appreciated

You are told that the function should have one input argument, but then you created a function with two input arguments: row and col. Here is a function with one input argument:
function out = odd_values(M)
... code here
end
Note that you do not need to assign to a temporary variable, you can simply assign to the output variable directly, so that code might look something like this:
out = M(1:2:end,1:2:end);
And now there is nothing else that you need to do except put it together.
