MATLAB: Problem with automized add_block destinations

Question

hello,

I am using the add_block function to automatize the creation of a model in simulink. I have stored the block names in a column of a table data, i would like to add the blocks and automatically change their names according to the string data of the table. Here is the code:

nL = numel(data.X)
for i=1:nl
    h=add_block('MyLibrary/BlockName' , ['MyModel/',data.Names(i)])
end

here is the error message:

"Invalid destination block specification."

data.Names is a string column of the table data. I have tried using another column of the table

for i=1:nl
    h=add_block('MyLibrary/BlockName' , ['MyModel/',num2str(data.X(i))])
end

and this works perfectly! What i am missing? please help! Thank you all!

Answer 1

Change the line to this

h=add_block('MyLibrary/BlockName' , ['MyModel/',char(data.Names(i))])
                                                %^ add char here
