TeX - LaTeX Asked on July 6, 2021
I am using the following code for summation with cases:
$sigma(x) = begin{cases}
1 if sum_{k=1}^{n} x_{k} > theta and i = 0
0, textit{otherwise}
end{cases}$
However for this code, there are no spaces between the characters when the LaTeX code is compiled. How do I insert space between the characters?
Thanks!
Use &
to separate the state from its explanation, and use text
to denote text mode.
$sigma(x) = begin{cases}
1 & text{if $sum_{k=1}^{n} x_{k} > theta$ and $i = 0$}
0 & text{otherwise}
end{cases}$
Syntactically, if $sum_{k=1}^{n} x_{k} > theta$ and $i = 0$
is a sentence, albeit a sentence that contains two formulas.
