Follow-up Comment #11, bug #41674 (project octave):

Another thought...

If you pass single arguments to a function like meshgrid, you get single
outputs.  But there appears to be no way to tell linspace to generate single
values instead of double.  Maybe we should consider an extension to Matlab so
that if the final argument of linspace may be a character string, either
"single" or "double" to specify the type of result that should be produced.

Would that help here?

I'm not sure why you need to use the isequal test.  Are you trying to check to
see whether single precision is sufficient for the given operations, or
whether double is needed because of the range of values?
