If that's not a viable option, one way to do it is to collect the rows or columns into cells using mat2cell or num2cell, then use cellfun to operate on the resulting cell array.
As an example, let's say you want to sum the columns of a matrix M. You can d...
What are type lambdas in Scala and what are their benefits?
...guments, but to implement Monad, you need to give it a type constructor of one argument. The solution to this is to use a type lambda:
class EitherMonad[A] extends Monad[({type λ[α] = Either[A, α]})#λ] {
def point[B](b: B): Either[A, B]
def bind[B, C](m: Either[A, B])(f: B => Either[A, C...

How to check if DST (Daylight Saving Time) is in effect, and if so, the offset?
...
This code uses the fact that getTimezoneOffset returns a greater value during Standard Time versus Daylight Saving Time (DST). Thus it determines the expected output during Standard Time, and it compares whether the output of the given date the same (Standard) o...
Is there an MD5 Fixed Point where md5(x) == x?
...
True, if you had to try every one. But you would only have to try every possible input to verify that there was no fixed point. If there is a fixed point (and Adam Rosenfield's answer suggests that there might be) then one lucky guess is all that's needed...
