Hello everyone,
I wanted to call a Java function using the Matlab function block in Simulink however i got this error:
Error:Undefined function or variable 'java.security.MessageDigest.getInstance'.
Function 'MATLAB Function' (#24.499.549), line 14, column 20:
"java.security.MessageDigest.getInstance('SHA-256')"
To solve it, I thought about packaging the Java call into a separate function and store it in the MATLAB Function block with coder.define extrinsic however, I do not know how to to declare a function as extrinsic and implement this in simulink.
If anyone has a solution, I would be very happy about your support.
Thank you in advance for your help.

Try using coder.extrinsic to declare the wrapper .m function as extrinsic in the Matlab Function block and call the java function from the wrapper function.
