Documentation

To compute an operation, you must drag the Dynamics into the equation. Dynamics and Scalar are listed on the left of the interface. These Dynamics are stored locally. If you want to add files, you can use the proper button. You can filter the Dynamics by name.

On the right you can see the "drop zone" buttons. You can distinguish between blue, red and yellow buttons: blue buttons allow you to add a Dynamic. Yellow buttons accept only scalar values and red buttons delete the whole operand.
Before the computation, you can define the name of the final result. When you are sure about the equation, click on Compute. If the operation is completed, you see the new Dynamic in the Dynamics list.
