Replicating "Timespan" of sim's backwards compatible syntax

TLDR: In short, what's the best way to rewrite time = 0:0.1:10; [T,X,Y] = sim('model',time) in the "modern" Simulink syntax that doesn't take an explicit time input? It appears I'm rather out of date w.r.t. my Simulink usage. The "current" syntax…

How can the output of a Simulink block be fed back as an input?

I have 2 embedded Matlab functions which I am using to create a Simulink model. Both functions use the output of the second function as their input. I am getting an error at the moment indicating that this is an invalid loop. Does anyone know how to…

How to get the order of Simulink blocks based on their pin connection?

For Example: From attached Simulink model figure (This model has no meaning. created only to give idea about my problem ), I want to get the order of blocks based on pin connection instead of their alphabetic order. The order should be like…

Heterogeneous data from workspace into Simulink

I have different matrices to import into a Simulink Matlab function from the workspace. These matrices have all different dimension, which I don´t know at priori. At the beginning I tried using the block 'constant' putting the data all together in a…

Why does Simulink start from a nonzero value?

I'm doing some simulations for control systems. I've noticed that the start time is not zero, even though in the parameters of simulation, the start time is set to zero. For example, in the following diagram, The output of the signal is with…

Does Simulink have a Compare to Constant block with the constant defined outside the block?

Consider Simulink's Compare to constant block. The constant to which you are comparing the input signal, has to be set in the Function block parameters window (double click on the block). Is there an other block that compares two input signals,…
