you can create global variables, or better, a global struct to hold our variables.
add
global struct_for_variables
right after the definition of your functions. Add it to your script too. Then, in your function, create a field for each variable:
struct_for_variables.var1 = var1; % where var1 is a variable to be accessed by the script or other function. you will be able to access and modify your variables from anywhere.
Another option, instead of a global struct, is to define the variables you need in the script as output parameters of your functions.
