MATLAB: How do you set the step time parameter of a step input from a mask

initializationmaskMATLABset_paramsetting paramatersimulinkstep inputstep time

It is possible to change the sample time using this code witin the initialization section of the mask (the mask is on a subsystem and the step input is within the subsystem):

TheBlock = gcb;

set_param([TheBlock '/Step'],'sampletime','3')

But when trying to use the equivalent code to change the step time, it does not work.

set_param([TheBlock '/Step'],'steptime','3')

Does anyone have any suggestions

Found out through trial and error that this is what works:

set_param([gcb '/Step'],'time','3')

Why do you think Reference is a parameter in a step bock. Like you see the parameters are

Step time
Initial value
Final value
Sample time
...

Even with those parameters you can't use set_param, to get the appropriate names of those parameters you can use

get_param('filename/Ref','dialogparameters')

ans =

              Time: [1x1 struct]
            Before: [1x1 struct]
             After: [1x1 struct]
        SampleTime: [1x1 struct]
    VectorParams1D: [1x1 struct]
         ZeroCross: [1x1 struct]

For your case

set_param('filname/Ref','after', num2str(step_value))
