CoolProp is a thermodynamic library which can be imported in several other programming environments.

Two possibilities are availbale:

• download the three files from sourceforge.net (only Linux 64-bit)
• compile the library following the instruction reported at coolprop.org

Copy the files libCoolProp.so and libCoolProp.so.* from CoolProp/build/ to scilab-*/lib/scilab/libCoolProp.so.

In the Scilab working directory, in which the CoolProp library is required, save the following propsi.sci file:

propsi.sci

link("libCoolProp.so", "propssi_", "c")
 
function out = PropsSI(output, input1, value1, input2, value2, name)
    out = call("propssi_",..
        output, 1, "c",..
        input1, 2, "c",..
        value1, 3, "d",..
        input2, 4, "c",..
        value2, 5, "d",..
        name, 6, "c",..
        "out", [1,1], 7, "d")
endfunction

Then, to call the library from a Scilab file, use:

exec("propsi.sci", -1)  // CoolProp library
