Assign value to variables

Hello,
I have a cell array with char: c={'R1', 'R2', 'R3','R4'}
and I have a vector b=[1 0 0 1]
how can i assign values for the elements of c, so whenever I type R1 in the workspace I get the value =1;
(note that I need this to run a simulink file)

"I have a cell array with char..."
But your example data here shows a non-scalar structure. Probably this does what you need:

Can you define variables with numbered names like X1, X2, X3, ... ? Yes.
Consider instead one of the other approaches, like a model workspace, described in this section of the documentation.

ck =
struct with fields:
R1R1: 1
R1R3: 1
R2R2: 0
R2R3: 0
R3R1: 1
R3R2: 0
R3R6: 0
R3R4: 1
R4R3: 1
R6R3: 0
R4R4: 1
R6R6: 0
R5R5: 0
R4R5: 0
R5R4: 0
R5R6: 0
R6R5: 0
I managed to store the data in a table, yet I need to get these values to workspace
For example after runing my mfile, if I write R6R5 i get 0 as answear, is it doable?
As I said you can do this but you should not. See the Answers post to which I linked for a more thorough explanation of why this is discouraged and (if you feel you must do this) how you would.
ok thank you sir, I'll check it

I'm not sure if this is helpful, but is seems to address the core issue you describe:
c={'R1', 'R2', 'R3', 'R4'};
b=[1 0 0 1];
z = input('Enter: ', 's');
b(strcmp(c,z)) % retrieve element from b in same position as user input in c
Sample run: (user input underlined)
Enter: R1
ans =
1
This isn't Simulink. It's just MATLAB code and Command Window interaction.
