In simulink model, I have a gain block and I want the value of this gain block to be a variable with the name x. The value of x changes over time and the formula for this is defined in a Matlab Function block. But whe the simulation is run it says that x is an undefined function or variable.

To do this, I would use a Multiply block instead of a gain block. Make x an output from your Matlab function block. Connect that output signal (x) to one port of the Multiply block and connect the signal to which you want to apply the gain to the other port on the Multiply block.

You first have to load the file declaring the variable into the workspace. You can just click on the error symbol and it will give suggestion to fix the error by loading the file into the workspace.
