simulink and m file connection

i have genetic algorithm written in m file and i want to run simulink from m file then read from simulink to m file the problem here is that i don't know how to read this value before the genetic algorithm running

[Azzi Abdelmalek]

How result in m-file is used in Simulink?

[mado]

the result of m file will be used in simulink after m file finished its iteration

Answer 1

[Azzi Abdelmalek]

In simulink model use from workspace block to read data from workspace and to workspace block to export data to workspace

[mado]

from workspace will send data after simulink have stopped but i need data before running m file as it depends on that variable after m file ends it will update simulink

[Azzi Abdelmalek]

Then Run your simulink model using to workspace block.

[mado]

from or to workspace are the same i can't use data till simulink finished running

[Azzi Abdelmalek]

This is not clear, can you explain ?

[Azzi Abdelmalek]

Ok then use Interpreted Matlab function block or Matlab function block (for code generation)

[mado]

why ?could you explain my code is colmplex and it contain calling function

[Jason Ghidella]

What you need to do is use set_param end to set the values of Simulink parameters from the GA objective function, and have an outport on the signal you want to read in the GA onjective function. Then you run the Simulink model using the sim function, and then look at the simulation output to get the value.

This video shows how to do this:

Answer 3

[mado]

for example if i used to workspace and i ran simulink the data won't be sent to workspace untill the simulink stopped

Answer 4

[Ramya]

can anyone tell me how to use the optimised values from the m file in simulink?
