I'm trying to create a function that will only accept a matrix

I'm not really sure how to go about this challenge. I know something is wrong with my output and function but I do not really know how to work it etc.

start
function output=rowcolumn(x,y)
if length(x)==length(y) disp('yes')
if length(x)>length(y) disp('no')
if length(x)<length(y) disp('no')
end

What is your problem?

Whatever you do avoid using length, as its output chagnes depending on the matrix orientation. Far more robust are numel and size for comparing the dimensions and number of elements.

Avoiding using length will be the first step to more robust code :)

I guess you’re testing for a vector lengths.

You need to use elseif to test the alternatives:

function output=rowcolumn(x,y)
if length(x)==length(y) disp('yes')
elseif length(x)>length(y) disp('no')
elseif length(x)<length(y) disp('no')
end
end
