I am trying to create a function that checks whether an element is a matrix or a vector.

I am trying to create a function that checks whether an element is a matrix or a vector. If it is a vector, it should return an error. If it is a matrix, it should check whether it is tall, square, or wide. I really don't have any start to this since I am very new to MATLAB.

Try with this:

function checkSize(A)
[m,n] = size(A);

if m == 1 || n == 1
    error('Input is a vector')
else
    if m > n
        fprintf('Matrix is tall\n')
    elseif m < n
        fprintf('Matrix is wide\n')
    else
        fprintf('Matrix is square\n')
    end
end

end

Please note that there are a number of ways this could have been done, the example above is just the quickest I could think of.
