Help with matlab

[tinch06]

Hello! I'm from Argentina. Excuse my english

I'm starting to work with matlab scripting and with the tutorials, but y can't to iniatilize variables.

I'm trying to plot a dot every time I call function "process" to show de "history" of the signal in the time. But if a write count = 0; (for example) the function initialize to zero every time. And if I don't write count = 0; the instruction count = count +1; doesn´t work.

I don't find the way to update the plot every time that xxxxx_process is called.

Sorry if this has already been discussed.


Thanks!

Hi Tinch, welcome aboard.

You can try declaring count as a global variable, either before the function declarations, or possibly like this,

Normal variables defined inside functions only persist for the duration of the function.


Good luck,

I didn't know about global variables.

I resolved my problem!

Thank you!
