Why when i load workspace manually the code works but when i try to load it from code doesn't?

Im trying to load some workspace variables for a neural network from code by using this

S0 = load('mynet.mat');

but when i run it i get this error:

Undefined function or variable 'myNet'.

Error in transfer (line 46)
nnet = myNet; % Load the neural net

If i am loading it manually and run it i have no problems. Why and how can i make it work from code?

You load your variable in a struct. Try

myNet=S0.myNet;

I need explications. why did this work? what is the difference? Also thanks. It worked

You can see your workspace in Matlab. Just take a look at it and you'll see your struct.

If you use load('mynet.mat') in command line you will load all variables in mynet.mat to your workspace. Hence myNet will exist if it is a variable in mynet.mat.

If you assign S0=load('mynet.mat') you will create a structure S0 that contains all variables stored in mynet.mat. myNet does not exist because it is part of S0.

myNet=S0.myNet; %creates a variable myNet with the content of S0.myNet

Additional to that: it is recommended to load into the output structure, and then access its fields. Read this to know why:

So the best solution is:

S = load(...)
S.myNet % access your data
