[Eeglablist] ERP data recode

[Yao Yutong]

Dear EEGlab Users,

I'm new to Matlab scripting as I was previously using only GUI version of
EEGLab. I was wondering if you can help me with scripting problem. I
suppose it's not very complicated, but I have a hard time finding the
solution.

I have had ERP data set with string event code. For example S1 S2 S3 S3
S5.I want to recode them into numbers. May I ask which command I can use
for this?

I would be grateful for any help!
Best wishes
