I have a Simulink diagram 'abc.slx' developed by a colleague. When I open the diagram, I get a warning:
Workspace for block diagram 'abc.slx' was not loaded because an error occurred while loading the MAT-file
'C:\Users\roger\Dropbox\etc\abc.mat'
Cannot reload workspace from non-existing data source file:
'C:\Users\roger\Dropbox\etc\abc.mat'
It's not surprising it can't load this .mat file: the path doesn't exist on my machine. I can't save the model, because I get a similar error.
What neither my colleague or I can figure out is how to remove the reference to this .mat file from the Simulink model. It doesn't need it, and as far as we can tell it only references data directly in the current workspace.
How can I find and delete the reference to this unnecessary .mat file?
Open the Model Explorer (View -> Model Explorer or Ctrl-H) and select Model Workspace underneath you 'abc' model. Change the Data Source from 'MAT-file' to 'Model file'.
Check this doc page for more information on the Model Workspace

I am trying to read SEED Dataset in EEGLAB. The files are in .mat format. I am getting the error as --- EEGLAB error in function pop_loadeeg() at line124.Output argument "accept" and maybe others not assigned during call to "F:eeglab2019\plugins\neuroscanio1.3\loadeeg.m>loadeeg".
How to read the .mat file of EEG SEED Dataset in EEGLAB ? Please guide.
I hope this help:
Run eeglab.m, next in the pop up window: file->import data -> using EEGLAB functions and plugins -> from ASCII/float file or Matlab array.
Almost you can check the tutorial in the official EEGLAB page.

I am trying to save real-time streaming data obtained from hardware to Matlab workspace, I use the following command: My issue is, it only saved the last set of data, but not all data.
To save all variables from the workspace in binary MAT-file, test.mat, type
save test.mat
When I tried with this
save('test.mat','-append'); ,
it makes my program halt, so I would like to know what is the correct way to achieve this?
They have same name and they are constantly overwritten, I did not get error message, I still get the file saved but I noticed that it only showed the latest set of data, what should I do to avoid this? I want it to save every set at each time step
The correct syntax for appending using save is
save(filename,variables,'-append')
This will save append all new variables and overwrite variables already in the filename.mat with the updated values.
If I define a stored procedure myStoredProcedure using Visual Studio Server Explorer in "Stored Procedures" folder, then I go to the .edmx to update the model.
I can use that myStoredProcedure in the code behind, and can be detected by IntelliSense, and works fine.
When I remove myStoredProcedure from the database and from the .edmx model.
It is still detected by IntelliSense. Even if it has no trace neither in Server Explorer -> "Stored Procedures" folder nor in .emdx "Stored Procedures / Functions" folder.
When it is used no compile error shown, but runtime error (Of course expected).
The function import 'DataEntities.myStoredProcedure' cannot be executed because it is not mapped to a store function.
If I re-define myStoredProcedure again in the Database -> Server Explorer -> "Stored Procedures", and update the .edmx model. The IntelliSense detects two:
myStoredProcedure -> this is the old one, and causes runtime error.
myStoredProcedure1 -> this is the new one, and works fine.
So how to correctly remove a stored procedure from DataEntities.edmx?
There's three places in the Model Browser that need objects deleted to completely remove a stored procedure.
1. Stored Procedures / Functions folder
2. Function Imports folder
3. Complex Types folder
Right Click on edmx--> Open with... --> XML (Text) Editor --> Find and remove all related xml blocks that refer to your procedures' name.
Open with XML Editor
Make sure you find and remove everything related to it.
Delete related xml blocks_1
Delete related xml blocks_2
If your procedure comes with a suffix _Result search also for everything without it and remove all xml blocks referred to it also.
After that hit Ctrl + S to save the edmx.
Now delete the cs related file named after your procedure under the .tt of your edmx
You can validate that the procedure is no longer mapped if you now open the .edmx normally from designer, click on it and hit Ctrl+s. If it would be still mapped it would be recreated.
I discovered the Refresh and Delete tabs on the EF Update Wizard recently. The Add tab is what you normally see but alongside the Refresh and Delete tabs. The Refresh tab is very quick and simple to use. ;)
i'm very new to matlab, i'm working on a software which needs the following files as input model.c,model.h,model_data.c for a particular simulink model. I have a model for which i can't generate model_data file using RTW, i have tried to get some information on the files generated by RTW, but i didnt get sufficient info. If there anybody who knows about the RTW please let me know the blocks which are required to generate model_data.c
thank you
model_data.c is a conditionally created file (i.e. it is only created if it is needed, which depends on the way the model is set up for code generation).
For a discussion of the Simulink Coder build process, and what files get generated when, search the doc for the section titled "Files and Folders Created by Build Process".
For others who need help in future.
Open the Configuration Parameters pane. Go to Code Generation -> Optimization and make sure that Default parameter behavior is set to Tunable.
I am going through someone's data analysis files (created in an older version of matlab) and trying to find out what a particular .mat file is that was used in a matlab script.
I am trying to load a .mat file in matlab. I want to see what is in it.
When I type...
load ('file.mat')
the file loads and I see two variables appear in the workspace. jobhelp and jobs.
When I try to open jobs by typing the following in the matlab command window...
jobs
the response is..
jobs =
[1x1 struct]
Does this mean that there is only a 1 x 1 structure in the .mat file? If so, how in the world do I see what it is? I'm even happy to load it in unix, but I don't know how to do that either. Any help would be greatly appreciated as I have a few files like this that I can't get any information from.
Again, a new user, so please make it simple.
Thanks
It means that jobs is a cell array {} and within this cell array is a structure defined
To see the structure and its contents type jobs{1}
I think you are dealing with a SPM5 Batch-File. This variable is an image of the tree-like structure you can see in the Batch-Editor of SPM. Your job consists of one subitem (stats) which could have various subsubitems (like fMRI model specification, model estimation and so on).
To access this structure on the command line just proceed like Nick said:
Each level is a separate cell array that you can access with {#} after the name of the level. Example: jobs{1} shows you that there is a subitem named stats.
Subitems in structs are accessed with a dot. Example: jobes{1}.stats{1} shows you the subitems of the stats-entry.
Notice that there could be more than one entry on each layer: A stats module could (and probably would) contain various subitems. You can access them via jobs{1}.stat{2}, jobs{1}.stats{3} and so on.
The last layer would be the interesting one for you: The structures in here is an image of the options you can choose in the batch-editor.
