Thanks. Could you please give me a hint on how to proceed with textscan?
The variable "stim_freq " is like (1685000000,1685630000,1686260000,1686890000,1687520000,1688150000,1688780000,.....) and the variable "stim_gd" is like (7.847651617E-009,7.840270671E-009,7.833383973E-009,7.826488771E-009,7.819906752E-009,7.813325228E-009,...).
Basically, I want to plot the elements of stim_freq vs elements of stim_gd.
