What is the Complex Vector Space L^2[a,b]?

[SeM]

Hi, I am using mathlib as such:

text...$\mathlib{L}^2[a,b]$...text

though, I get the error:

<recently read> \mathlib l.235 ...d form the complex vector space $\mathlib {L}^2[a,b]$ which satisfie... The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined. [9] ! Undefined control sequence. <recently read> \mathlib
