Code for Monotonically increasing function

Hi All,

Can anyone check the following code snippet and tell me why it fails for the following test cases?

x = cumsum(rand(1,100));

x= [ -3 -2 -1 0 1 2 3]

function tf = mono_increase(x)

for ii=1:length(x)

for jj=(ii+1):length(x)

if x(ii)<x(jj)

tf = true;

else

tf = false;

end

end

end

end

I'm getting the desired result in my laptop but with the compiler of MATLAB , I'm getting error.

Please someone tell me how to resolve it.
