Hi, I'm trying to integrate my c code to simulink.
I made a header file and a source file named file.h and file.c.
and there is a function named function1 and the code is stated below.
static double a;
a = a+1;
Next, I made a C caller block and typed like below.
After that, I ran my code and the error is stated like this.
In line 1:error: 223, function "function1" declared implicitly
How can I solve this error?
