Hello,
I've noted that the function str2double() only works with exponent
identifier as 'e' or 'E', but not with 'd' or 'D', that are common
identifiers in files generated using Fortran. Then
str2double('1e2') is 100, but
str2double('1d2') is NaN
This behavior is the same in Octave as well as Matlab. Exists any
technical reason in order to not consider the identifiers 'd' or 'D'
for the conversion of the reason of the Octave's behavior is for
matching the Matlab's one?
I find str2double() more convenient in a task than str2num() as the
first one is faster, but my dataset uses 'D' as exponent identifier
str2double is a compiled function, but str2num uses eval which will be a lot slower as you say.
You would almost certainly find it faster to first replace 'd' with 'e'. e.g.:
function d= mystr2double(d)
d(d == 'd')='e';
d = str2double(d);
endfunction
