How to create Data.mat file for Convex.jl to solve optimal power flow using Matpower?

I’m a newbie learning Julia for optimal power flow formulation using convex optimization. I came across an example from Convex.jl documentation in here

In the example code the used “Data.mat” for the system parameters. I want to know how can I create the Data.mat file for any system provided in the Data folder of Matpower?
Thank you.
