Hello

In the following, I need $$1\leq m\leq M$$ to be exactly under "arg", How can I do that?

$$I=\text{arg}_{\substack{1\leq m\leq M}$$

Hi S_David,

Code (Text):

I=\mathop{\mbox{arg}}_{1\le m \le M}

which gives:

$$I=\mathop{\mbox{arg}}_{1\le m \le M}$$

Re: Latex Help

Thanks alphysicist for replying, but the code you gave did not work in my case. I forgot to mention this expression is an in-line expression, I don't know if this has anything to do with the problem.

Best regards

Re: Latex Help

You can force it by using displaystyle:

Code (Text):

I=\displaystyle{\mathop{\mbox{arg}}_{1\le m \le M}}

but of course that will put extra spacing between the lines of your text.

Re: Latex Help

Why do you want this to appear under "arg" anyway? If you want the minimum or maximum value over a range of arguments, then it would be underneath "min" or "max," and if you want the argument that results in the minimum or maximum of the expression, then it should be "argmin" or "argmax", but what the heck is just "arg" ?

Re: Latex Help

I neither want the argument of max nor min values, I need the argument of an arbitrary value m. Of cource, I didn't write the whole expression because it doesn't affect what I want.
