Initialize fail for HEOS in mixture with Argon and CarbonDioxide (in Matlab)

[xaumex]

Hi,

If you try to compute a mixture with Argon and CarbonDioxide in its components, for example

CoolProp.PropsSI('D','T',298.15,'P',101325,'HEOS::Argon[0.5]&CarbonDioxide[0.5]')

the following error appears:
Warning: Initialize failed for backend: "HEOS", fluid:
"Argon[0.5]&CarbonDioxide[0.5]" fractions "[ 0.5000000000,
0.5000000000 ]"; error: n could not be matched in get_double_vector

I found this error in Coolprop wrapper of Matlab (v5.0.5 and 5.0.4). I'm using Matlab R2013b in win64 arch.
I don't know if the error is in the matlab wrapper or in coolprop.

Thank you

That looks like a bug. I'll try to fix it today.

It's a bug with that particular binary pair. Others seem to work fine.
