21 Nov 2009 bench.dat Update the data file for BENCH..M Author: Steven Lord Espinosa, Gabe

Hi Steven,
Unfortunatlly I update these files, but didn't check the release version. Could you please help me with the R2007a Version?

The function RandStream in this version does not exist.

Thanks in Advance,

Gabriel

Good One .!

As 07 Sep comment says, this function gives incorrect results because of an unnecessary conversion to char.

Hi how's it going Steve,

On line 19, you have:
number=num2str(number);

but this will return a string with fewer decimal places than is necessary to represent the actual machine number that was input.

For example, if I were to do
>>[s,e,m] = num2ieee(sqrt(2))
then the string on line 19 becomes '1.4142' and I get a wrong result (at least that's what happens on R2009a and R2009b).

Changing line 19 to:
number=num2str(number,100);

or something like that would be the only change needed, I think.

Fine example, Steven.
 
How can I pass a value to an argument out of the function red_blue?

For instance, I would like to be able to call the function as COLOR=red_blue() in another code, and get for COLOR whatever color I choose by clicking.
