Masking and base workspace

I have a structure called "uwb" in base workspace. Under uwb structure I have another structure called "channel". Under channel I have got two variables a & b . Now I want to create a subsystem. I want to mask the block. My problem is I have to use the variables a & b for the initialization of the masked subsystem. How can I include a & b in initialization commands of the subsystem while masking.

Answer 1

[TAB]

Initialization commands cannot access base workspace variables, it can only access the variables from Mask workspace.

Pass two more values from the subsystem mask say init_a & init_b.

In initializarion pane write

a = init_a;
b = init_b;

In the parameters dialog pass-

init_a as --> uwb.channel.a

and

init_b as --> uwb.channel.b

Not sure if I understand your question correctly, but try this in your Mask Initialization:

   a = uwb.channel.a;   
   b = uwb.channel.b;

Sorry for not making myself clear but i have already done that and it doesnt work.

Rephrasing

** can I use the variables of base wrkspace directly in the initialization of masked block ???or I have to do some change in the dialog parameter tab ??

***I have a structure called "uwb" in base workspace. Under uwb structure I have another structure called "channel". Under channel I have got two variables a & b . Now I want to create a subsystem. I want to mask the "subsystem".

I am having two mask parameters (under the masked subsystem) chan & ch_idx. I have to assign uwb.channel.a & uwb.channel.b to the variables chan & ch_idx respectively in the initialization commands.

TAB's answer is the right solution for you.
