Math & Science ⇒ \in not working as expected

For a range block $R_i$, we calculate $s_i$, $o_i$ using the equations 4.2 and 4.3 and find the best matching domain block (for which the rms is minimum) in the same way as in previous method. Apply $s_i$ and $o_i$ on the first pixel $a_1$ of domain block to produce new range pixel ${b_{1_{new}}}$. Now, apply $s_i$ and $o_i$ to the next pixel $a_k$\in $\{a_2,a_3,...,a_n\}$ producing a value ${b_{k_{new}}}$. This new value bknew should not be equal to ${b_{1_{new}}}$. If they are equal we take the next pixel of domain block and produce new bknew until that is not equal to b1new. If ${b_{k_{new}}}$  \in $\{0,1,...,255\}$ 
we skip this pixel. We now calculate {s_{i_{new}}} and {o_{i_{new}}} as follows:

Hi guys,

\in is a mathematical construct and as such belongs into a mathematical environment. I added some more information for you inside the code, just have a look by clicking on Open in Writelatex.

For a range block $R_i$, we calculate $s_i$, $o_i$ using the 
equations 4.2 and 4.3 and find the best matching domain block 
(for which the rms is minimum) in the same way as in previous 
method. Apply $s_i$ and $o_i$ on the first pixel $a_1$ of 
domain block to produce new range pixel ${b_{1_{new}}}$. Now,

\dots,a_n\}$ producing a value ${b_{k_{new}}}$. This new value 
bknew should not be equal to ${b_{1_{new}}}$. If they are equal 
we take the next pixel of domain block and produce new bknew

\section{FYI}
You can automatically number and reference equations, just like 
you can do with tables and figures. This is much more reliable, 
changes are easier. For example, the Pythagorean theorem is shown 
in equation~\ref{eq:pythagoras}, you can do this with 
autocite, too: \autoref{eq:pythagoras}

\begin{equation}
a^2 + b^2 = c^2
\label{eq:pythagoras}
\end{equation}

I strongly recommend to do some basic reading. A question like this can be answered very easy by just reading some introductory material. This saves you a lot of time instead of waiting for an answer here. I know that you don't want to hear that, but it's a fact.

Furthermore we would appreciate it very much if you describe the problem with some additional words and the relevant error messages from the log file (*.log). And it is essential that you cut the problem down to a proper minimal example. All these things belong to an adequate problem description. You have been already told so already in your other questions. We don't want to repeat this for every question. Otherwise it can happen that you only get back code without any comments or no answer at all. We are no dogs here to which you can simply chuck a bone.

And just for your information, a proper example that demonstrates the problem could look like this.

Code: Select all

\documentclass[12pt,journal,compsoc]{IEEEtran}

\begin{document}
  \in
\end{document}

So, please do not call an example minimal if it is far from being one.
