define variable value in simulink model

Hi,
I use variable 'L' inside gain block.
How can I define the value for 'L' without using the command window in Matlab? I want the user can edit the variable value In the model, something like in the added image. <<

Thank you!

Use "Model Explorer" from View Option . Then Select Simulink Parameter and Add. Then Rename the 'Parameter' with the variable you set in the Simulation and write the 'value', close the window.
Then RUN the simulation, it will take the values of the Gain Block directly, no need to write the values in the Command Window.

Instead of a Gain, use a divide(product) block. First argument is the signal, Second will be from a data store read (the pair of data store write).

It depends on what is meant by "the user can edit the variable value In the model". If you want the user to be able to directly modify L on the block, then you can create a mask for the block and make "L" a mask parameter. Now "L" is modifyable directly on the block dialog.
In the picture you show a Constant block feeding into a Datastore Memory block. In most cases, we would not recommend setting the value of a parameter (like L), with the value of a signal (like the output of a constant block). See the page below for the difference between parameters and signals, and how to use the parameter writer block if you really need to do this.
