How to change the data type?

Hi I used Matlab simulink file.

I use the two type simulation.

1.type 1

1) solver type : variable step

2) simulation type and sample time : discrete, 1e-6

2. type 2

1) solver type : fixed type

2) simulation type : continuous

I want to use type 1 output data for type 2 input data

And the data is updata at every 1 second in type 2.

How to make this simulation in type 2?

Any time you have aa continuous system there should be an associated mathematical model of the system . To introduce discrete samples into a continuous system then your mathematical model needs to use something equivalent to Dirac Delta or Heaviside function . But to calculate continuous systems properly much of the time you need to be able to calculate derivatives . Now , how do you want to define the instantaneous derivative of dirac or heaviside right at the transition times ?
