The problem is something like this:
V_table =
8×4 table
Variable lb initial_val ub
_____________ ____ ___________ ____
{'Lser_B7Tx'} 0 0.4 2
{'Lser_B7Rx'} 0 0.4 2
{'QCsmd' } 30 70 80
{'QLemb' } 30 60 80
{'Lshu_B7' } 0 4 10
{'fQ' } 2000 2500 3000
{'Cshu_B7' } 0 0.01 2
{'QLsmd' } 30 60 80
This is code I am using for what I try to achieve i.e. to store the values such as 0.4,0.4,....(initial_value) to variables Lser_B7Tx', 'Lser_B7Rx'......'QLsmd'.
for i = 1:length((V_table.Variable)
V_table.Variable{i} = V_table.initial_val{i}
V_table.Variable
end
But I am getting the error : Error using nport_B7DPX (line 125)
Brace indexing is not supported for variables of this type.
Would anyone please let me know how can I assign value to the variables of cell array

% your V_table:
V_table = table( ...
{'Lser_B7Tx';'Lser_B7Rx';'QCsmd';'QLemb';'Lshu_B7';'fQ';'Cshu_B7';'QLsmd'}, ...
[0;0;30;30;0;2000;0;30], ...
[0.4;0.4;70;60;4;2500;0.01;60], ...
[2;2;80;80;10;3000;2;80], ...
'VariableNames',{'Variable','lb','initial_val','ub'})
Instead of making a bunch of different variables in your workspace that contain all the same information of what's already in the table, you can redefine your table slightly, so that the Variable column is the RowNames of the table:
V_table.Properties.RowNames = V_table.Variable;
V_table.Variable = []
Then you can get easily whatever you need, by indexing with a row name and a column name:
V_table{'fQ','lb'}
V_table{'QLsmd','initial_val'}
V_table{'QCsmd','ub'}

There's a backslash missing before the last w you added. I included that backslash, and I removed the tokens because it doesn't seem like you need them. Does this do what you want now?
data = { ...
'PORT 23 P=1 Z=50'
'PORT 12 P=2 Z=50 PIN_ID=CB7TX'
'PORT 13 P=3 Z=50 PIN_ID=CB7RX'
'PORT 14 P=4 Z=50 PIN_ID=CB66TX'
'PORT 15 P=5 Z=50 PIN_ID=CB25TX'
'PORT 16 P=6 Z=50 PIN_ID=CB25RX'
'PORT 22 P=7 Z=50 PIN_ID=CB66RX'
};
port_match3 = regexp(data, ...
'PORT\s+\d+\s+\w+=\d+\s+\w+=\d+\s\w+=\w+','match')
port_match3{:}
