how to find the parameter name for any block in the simulink to use it in set_param command?

I want to set a value of 5 in the "step time" parameter in the "step" block from the mfile, the name of the model of simulink is "plant1"

i wrote in the command window:

set_param('plant1/Step','step time',5)

but there is an error:

Step block does not have a parameter named 'step time'

my question: what is the name of the 'step time' parameter which can be used in set_param command?

and, in general how can i reach to the name of each parameter in each block easily?

To programmatically find out what parameters a block has, get its handle:

h = get_param(gcb, 'Handle');

or

h = gcbh;

and then use the get command to see a list of all its parameters and their current values:

get(h)

You can also take a look at the Block-Specific Parameters page. The parameter names are listed, as well as their possible values.
