MATLAB: How can i send constant input values to workspace from simulink model

MATLABsimulink

how can i send constant input values to workspace from simulink model and later how can i use those variables in mfile, do some changes to them and then sending it back to simulink model?

If you are using a constant block, it's more logical if you define your constant c in windows command or in your m-file which you need to run before starting your simulation, and set your constant bloc value to c.

As far as I know, edit text blocks takes input arguments as string. What you need to do is to use set_param command and convert the variables to double by using str2double command.

We have had a previous discussion about it, so please refer to that discussion. Here is an example:

set_param('gui/Constant','Value','i')
set_param('gui/Constant1','Value','j')

Do not forget to convert these values to double.

I suppose the observation "gradual decrease" is just a misinterpretation. If you see this in the scope block, Simulink interpolates between (4.9,1) and (5.0,0), but for the simulation, there is something existing between 4.9s and 5.0s.

If you like to changes the vizualization, simply select a smaller step size. But IMHO - the technical constraints shall determine the step size, not the need for good looking.
