How can I write a forward slash in a label

I tried to write forward slash in the label of an axes.

here is the code:

ylabel('\alpha-helix fold induction (TFE / H_2O)')

In the plot it results in a fraction bar. How can I write a forward slash?

I think i as something in common with the _ for the H2O. Because also when i removed the / the label is not nice displayed.

I'm not sure what you mean. The slash between the E and the H? It's a forward slash for me, see:

Is that not what you want?

You can use the same technique as for underscores in latex: http://www.mathworks.com/matlabcentral/newsreader/view_thread/54919

Thanks a lot for this hint. Also good to know. I would like th have the 2 as a index. In the plot it's ok. but after the export to eps the label looks really bad. words over words.

What do you mean by "index"? And can you give an image of how you want it to look, like I did above?

Which MATLAB are you using? There was a similar problem in R2008b for some platforms. If you are using R2014b or later, then possibly http://www.mathworks.com/matlabcentral/answers/159732-2014b-axis-label-errors-when-printing-to-postscript will help.
