Changing a .GAMBL file to a .MAT file

hello,

So I am trying to use a code someone wrote to find an integral of angular velocity and I tried to just switch my file out for theirs and run it but my file won't work because it is a .GAMBL file.

https://drive.google.com/file/d/1Y4E0y16Hw2dWQjwXSA5ejCpaLGtuz_pN/view?usp=sharing

^ that is the file.

I am super new to this but love engineering and I need this to help with my physics project on boat stability.

D = load('barge1.gambl');
AngularVelocity = D.AngularVelocity;
tv = AngularVelocity.time;
pv = AngularVelocity.x;
qv = AngularVelocity.y;
