code is showing error with some inputs

function w=flip_it(v)
m=size(v)
w=v(end:-1:v(1,1));
end

[James Tursa]

Is this supposed to work on vectors and matrices and multi-dimensional arrays?

And what is the point of

m=size(v)

which is completely unused.

In any case, there are many inputs with which the given work will not work, something as simple as v=0 will error, but since there's no explanation of what the code should do how can we tell what is a coding error.

Why are you using v(1:1) as an index into v? Did you mean this instead?

w = v(end:-1:1);

Also, it is not clear from your post whether your code is supposed to work for only vectors, or for matrices and multi-dimensional arrays also. If it is the latter, then you will need different code to handle those extra dimensions properly.
