Hi feng,
In MATLAB R2023b, the Signal Builder block is considered outdated, and it is recommended to use the 'Signal Editor' block instead. The Signal Editor block provides a more modern and flexible way to manage and edit signal data.
If you have scripts that directly create Signal Builder blocks and you encounter issues with them in MATLAB R2023b, you can convert your Signal Builder data to be compatible with the Signal Editor block.
For moe information on Signal Editor block refer following documentation:
