XSteam('rho_pT',1.5287,111.9187)
is showing as NaN. Please let me know the reason.

Not only density but all other properties are being shown as NaN

Thank you Magnus for this. I would like to use this with Simulink, however, I'm not able to.. The code I'm using is as follows but I'm getting errors:

function h10 = fcn(t10)
h10=XSteam('hV_T',t10);

Would appreciate if anyone can help.

I can not connect to x steam site. Got the following error message:

You might be able to increase speed for long loops by calling XSteam using arrayfun (http://www.mathworks.com/help/matlab/ref/arrayfun.html) or use IAPWS_IF97 (http://www.mathworks.com/matlabcentral/fileexchange/35710-iapwsif97-functional-form-with-no-slip)

@Daniel Vecchio - you might try NIST Chem WebBook (http://webbook.nist.gov/chemistry/fluid/), EES from the University of Wisconsin (http://fchart.com/ees/), TRNSYS also from Wisconsin (http://sel.me.wisc.edu/trnsys/) or Aspen (http://www.aspentech.com/products/aspen-properties.aspx). Good luck and post your findings to help others.
