How to use XSteam m-file with Simulink?

Hello everyone, I'm trying to use XSteam m-file with Simulink. The code that I'm using inside the MATLAB Function block goes as follows:

function h10 = fcn(t10)
%#codegen
coder.extrinsic('XSteam');
h10 = coder.nullcopy(zeros(size(t10)));
h10=XSteam('hV_T',t10);

With this, I'm not getting the output 'h10' and I'm getting the following error:

Making simulation target "SSubstitution_sfun", ...  
/bin/bash: /Applications/MATLAB: No such file or directory

I'm getting my answer with simply writing the following in MATLAB's Command Window:

XSteam('hV_T',4.5)
ans =
 2.5092e+03

as t10=4.5 and h10=2.5092e+03. Would really appreciate your help guys. Thanks

Hello There,

I am sorry to answer this question only five years after you posted, but here is how to use the XSteam library within Simulink:

You will have to use the level2 S-Function block.

within that block, on the Outputs section you can use the XSteam, or any other (I believe) matlab function.

Using the level2 S-function looks complicated but following this youtube video might help a lot:

In my case I was able to use the XSteam function within another code inside Simulink.
