Hi guys, I created two functions, in the second one I'd like to read the data from the first one like this but in a smarter way, is it possible to use a loop somehow here? I'd like to read from t1 till t4 and from y1 till y50 and it's not convinient to write every single variable.

t1=model.t1;
t2=model.t2;
t3=model.t3;
t4=model.t4;
y1=model.y1;
y2=model.y2;
y3=model.y3;
y4=model.y4;
y5=model.y5;
y6=model.y6;
y7=model.y7;
y8=model.y8;
y9=model.y9;
y10=model.y10;

Use arrays and/or named fields instead -- don't create a sequence of variable names like this to begin with.

As per my understanding you want to send/access data from one function file to another function file.

You can go through the documentation below to see different ways of achieving that.

Documentation link

However, as you want to access many different variables try to put all those variables into a cell array and pass that as function arguments.

You can send this cell array to any function as argument and can access that from that function.

e.g.:

>>my_variables={t1, t2,t3, t4.......}

t1, t2 are variables in func1 and you want to access these in func2

then create cell array in func1 with t1, t2 as members and send cell array as argument to func2 from func1.

Here is an alternate solution:

If you do not want both functions to work simultaneously then you can save all the variables from workspace into a “.m“ file using save command and can load all these variables into workspace using load command.

Hope it helps!
