Matlab Syntax [message #37146]

Folks,

Speaking of Matlab syntax (which I am beginning to like,
by the way), here is one I find confusing. Any Matlab
users out there in IDL-land?

y(2*x(IDX==0))=[];

IDX is a vector, I think. The variables x and y
are vectors for sure. I realize IDL doesn't
have a null array, but my best guess about this
translation is something like this.

I = Where(IDX EQ 0, count)
IF count GT 0 THEN y[2*x[I]] = !Values.F_NAN

Is that close?

Cheers,

David
