Hi, I am trying to replace existing dataset in a signal builder block in Simulink model, on appending new datasets to it which has 'n' number of signals programmatically using Matlab script. Any feedback on how the existing dataset can be replaced is appreciated.

Hi Geethika,

You can use the "signalbuilder" function with the "set" option if you want to replace the existing dataset, or use the "appendsignal" or "appendgroup" options if you would like to append signals or groups.

You can check out the following documentation link to learn more about the "signalbuilder" function and its options:

Additionally, usage of "signalbuilder" is not recommended by MathWorks, and you might want to replace it with "signaleditor".

You can read more about the "signaleditor" block and how to migrate from the Signal Builder block to the Signal Editor block by going through the following documentation links:
