I can use both blocks for getting output from simulink to matlab, but if there are two of them there should be difference in the way they are used but I can not figure it out.enter image description here

Using an Outport block allows you to,

  • use your model as a Model Reference
  • when generating code (using Simulink Coder) from the model, interface the model with other code

If you're not needing to do either of the above - for instance you only want to dump data to the MATLAB Workspace - then the To Workspace block is arguably easier to use. Plus it shows the user what the resulting variable will be without them having to open the model properties window.

Note also that To Workspace can be used at any level of model hierarchy, whereas Outport can only be used to get data out of the highest level of a model. (Outport are used in SubSystems but to interface a sub-level of a model to a higher level, not to get data out of the model.)
