What is the formula for calculating the number of bytes to createjmf_jmf_ a file for mapping for a pre-known sized array of a given type?
require 'jmf' NX =. 10 NY =. 10 nbytes=: 7!:5 <'tmp' [ tmp=. 1p1 $~ NX,NY NB. my estimate of number of bytes for 10x10 array of floats createjmf_jmf_ '/tmp/tmp';nbytes (JFL;NX) map_jmf_ 'tmp';'/tmp/tmp' ](NX,NY) NB. the shape I want 10 10 ]$ tmp NB. not the shape I wanted 19 10 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
