[ncl-talk] A comment on an error message

[Dennis Shea]

ncl 0> x = *random_normal*(0,5, (/2,3,4,5/))
ncl 1> printVarSummary(x)                          ; <== ; 4D ==> [2] x [3]
x [4] x [5]
ncl 2> printVarSummary(x(:,*1*,:,:))                ; <== ; 3D ==> [2] x
[4] x [5]

NCL treats a dimension of size 1 as a *degenerate dimension.*
NCL silently acts like Matlab's  *squeeze*
