Dear Bhanu,

welcome,

To generate data bursts you can use random number generators function in mat lab and its controls. For code examples please refer to the Matlab page:https://www.mathworks.com/help/matlab/random-number-generation.htm

Best wishes

It strictly depends on what you mean with “bursty” and what kind of data you want to generate. If you provide some additional details it may help

If you mean generating random data for test in matlab there is a function rand to generate data with any number you want
