I created a 32bit C# simple application with VS2017:
static void Main(string[] args)
{
try
{
var matlab = new MatlabFunction();
double[] data = { 1, 2, 3 };
double[,] r = (double[,])matlab.doMedian(data.ToArray());
Console.Out.Write("OK: " + r.ToString());
} catch( Exception ex )
{
Console.Out.Write(ex.ToString());
}
Console.ReadLine();
}
This program work on many win10 with MRC v8.0 installed, but on one system I have :
System.Exception:
... MWMCR::EvaluateFunction error ...
Undefined function 'doMedian' for input arguments of type 'double'..
at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn)
at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Object[] argsIn)
at MatlabFunctionNative.MatlabFunction.doMedian(Object input)
at TestConMatlab.Program.Main(String[] args) in C:\Users\User\source\repos\TestConMatlab\Program.cs:line 18
Of course I have installed the same Matlab MCR v8.0 x86. I have trace some API call with procmon but I did not find solution.

I have deleted the folder C:\Users\%USER%\AppData\Local\Temp\%USER%\mcrCache8.0. Remove MCR and delete manualy C:\Program Files (x86)\MATLAB, and after restart, program work !
