coffeescript

Hi everyone, I'm trying to find an elegant way in Coffeescript to merge an array of arrays, so that [[1,2,3],[4,5,6],[7,8,9]] ==> [1,2,3,4,5,6,7,8,9].

As you might imagine, I need this because I'm generating arrays from a function in a "for in" construct and need to concatenate the resulting nested array:

result = (generate_array(x) for x in arr)

Is there an elegant way to handle this? Thanks for any pointers!

I'm going through a Fortran code, and one bit has me a little puzzled. There is a subroutine, say SUBROUTINE SSUB(X,...) REAL*8 X(0:N1,1:N2,0:N3-1),... ... RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
