Can anyone recommend a good linear algebra book?

QuoteOriginally posted by: CuchulainnGilbert Strang, one of the bestI agree, his book is one of the best for (undergraduate) self-study. As an additional bonus you can watch his video lectures which more or less follow the book.

linux: "dmask," "htab" (fstab?) - do these words mean anything to you?

<t>Is is a storage device? There is "dmask" option that you can specify in /etc/fstab for certain filesystems. It tells the appropriate mount program to use specific mask for directories. For instance (from "man mount", section for FAT): dmask=value Set the umask applied to directories only. The def...

MBS effective duration question

<t>Correct. Normally current coupon and one or more market rates (treasury, libor) are inputs to prepayment model. When calculating effective duration you shift the market rates (and keep oas constant for discounting) but you don't know what the current coupon will be. So the standard assumption is ...
