is this a bug because it definitely looks like

Hi everyone,

So I'm trying to do quite a simple task with matlab. I have an array defined as array=[-5:0.1:5] and I want to find the position of a particular element using find. for example find(-0.1==array) should return me the position of the element -0.1 in the array, but it doesn't. What's more strange is that if I ask matlab (-0.1==array(50)) it will return FALSE! I tried defining the array as [-5:0.1:5], (-5:0.1:5) or with no brackets whatsoever but nothing worked. Help please?

Thank you very much and I look forward to your comments.

Kind Regards, Alex
