I need to

Write a function named LONGER that will use two argument vectors and return the argument vector that has the longer length (greatest number of elements).  Do not display the vectors in the function.  Include a description in the function help line. Syntax counts.

I have

function output= longer(x,y)
if output=max(numl(x)>y)
else output=max(num1(x)<y)
end

is that right?

Assignment is not permitted in the condition part of an "if" statement.

"numl" is not defined in your code. The name is similar, though, to the MATLAB function numel()

No. Adding 1 to the elements of x has no connection to returning the vector which has more elements. If those x and y vectors were input, then x should be returned because x has 6 elements and y only has 3 elements. You aren't even examining y at all before you return x+1 so how could your function possibly know which is longer ??

Also, you should be accepting x and y as input arguments, not giving values for them in the function.
