Hello,
Is there is a way to return error message over mulitple expressions or do I need to split each expression into try & catch.
example code
try
exp1
..... exp 50
end
Expected Output
exp5 NOK
exp 20 NOK

I am not sure what you mean.
the try catch block will catch any exception. If the exception is in the first line of code, the rest of the code will not be executed. if there is no exception, then catch block will not be run.

You need try/catch around the execution of each statement that needs separate handling.
If you are able to put the code for each into a function handle, then you can create a cell array of function handles and then loop
for idx = 1 : length(fncs)
try
fncs{idx}(arguments) ;
catch
report it
end
end
