test_number=evstr(test_str)
It looks like working but it takes a not acceptable time...
Do you have a more clever idea?
You might try strtod()
Right.
evstr() is slower mainly because, historically, it includes some
concatenation features that enables it not working in an element-wise
way, like with
--> evstr(["1:3" "4" ; "5" "7:9"])
ans =
1. 2. 3. 4.
5. 7. 8. 9.
This was an unexpected (and undocumented) complication when debugging
and upgrading
evstr() 2 years ago. We had to (temporarily) renounce to some
element-wise processing.
However, in order to avoid breaking the back-compatibility, such a
element-wise processing
could be implemented through a"by-element" optional flag. Then, the
sizes of the input and
output would match, and some related bugs like the 10196
<http://bugzilla.scilab.org/show_bug.cgi?id=10196> could be fixed, at last.
