To workspace block I have most of it understood but one part. Assume you added a mask parameter called 'VarNum' which is an 'edit' type, and the name of the "To Workspace" block inside is still called "To Workspace", you can add the following line in the "Dialog callback" of the mask parameter 'VarNum'. However, the sample time for the To File That block is used to get data defined in the Scilab workspace and use them in Xcos. that is inconveniant to deal with since it always saved as 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. Once I put clock block and to workspace block, time length was 1 by 51! I used 2D array in to workspace block, still I got 3D array! It is related to time! I even defined t as input to the function, again I received 3D array! However, all that aside one of the best blocks in Simulink is the To Workspace block. You will have to figure out if there is already a block there, decide whether to disconnect it, etc. Then in the command window use for example "plot(t1,x1,t2,x2)" to plot them on the same figure. So the signal that you output to the workspace has the size 90. By the way, the one you have is timeseries. Looking at the doc for the Array setting: If the input signal is a scalar or a vector, each input sample is output as a row of the array. The Playback block presents three options to add data: add a workspace variable, add a file, or open the Add Signals dialog box for more options, such as adding One From Workspace block uses default values for all block settings, and the other is configured to load data for a bus. The variables y and t appear in the workspace when the simulation is complete. Signals connected to a Record block always log to the Simulation Data Inspector. By default, the block does not create a timeseries object. I simulate my Simulink model using the SIM command from a MATLAB function or a GUI created using GUIDE. Membership.
