Matlab simulink call function how to use global variables
smulink can easily build a system model, through the use of function can transplant C code, verify the actual discrete system performance.
Matlab function box is as follows:
1. First define the global variable global; create a new variable a through Edit Data, and select Data store memory for the attribute Scope
2. Open the global variable definition box through simulink View-》 Model · Explore ——》 Base · Workspace,
3. Create a new variable a and set the variable to be an attribute. Here it is set to doulbe type, initial value is 0, real number is real. At this point, the variables in the matlab function module have been defined as global variables, and can be called and saved in multiple places for the simulink file.
4. The complete model is as follows:
5. Data after operation
