Why does my plot line appear outside the axes?
I’m trying to make a double y-axis plot of data that extends beyond the x-axis limits of the plot. When I save the plot as a .png, the plot lines appear outside the right axis of the plot.
Here’s code for a simplified version of what I’m trying that produces the issue:
x = [0 1 2 3 4];
yl = [0 1 2 4 3];
yr = [0 2 3 1 2];
yyaxis left
plot(x, yl)
yyaxis right
plot(x, yr)
xlim([1 3])
saveas(gcf,'[PATH].png’)
And here’s the image that’s saved:
I know that there’s a workaround of shortening the data arrays to the range of the x-axis limits before plotting, but I was wondering if there’s a more elegant solution.I’m trying to make a double y-axis plot of data that extends beyond the x-axis limits of the plot.

How to add warning message when using simulink and code generation?
Hi!
I’m trying to add a custom warning message into a simulink model, which also should be able to work with code generation. I’ve got no luck in finding a function or how to add such message without the model crashing. I’ve tried the function warning and sldiagviewer.reportWarning in a matlab function block, but they are not compatible with code generation and I receive the error: "The ‘sldiagviewer’ class does not support code generation" or "Function ‘warning’ not supported for code generation.". Could this be solved in some way?

How do I manage Speedgoat software version mismatches in a standalone SLRT app deployed with MATLAB Compiler?
When operating a Speedgoat target computer from a development computer, both must have the following matching set of software:MATLAB release and update versionSpeedgoat I/O Blockset versionSimulink Real-Time Target Support Package version
If this is not the case, a "Target computer software version mismatch" error is thrown when trying to connect to the target:
Unable to connect to target computer ‘TargetPC1’:

When connecting to a Speedgoat from a full MATLAB installation, the user can simply start the software update from SLRT Explorer or the MATLAB command window.

Error trying to start Simulink from m-file.
In an SImulink model I had two scripts as my Model initializaiton functions (those are called "Achs-Data" and "Init_Sim"). I need to write a new script which runs those two scripts (so I get the variables I need to run Simulink in the workspace) and then starts the simulation. (I can’t keep them as the InitFcn’s because after the simulation finishes some parameters should be changed an the simulations has to be repeated).
So if i start those scripts in my new script by calling their names (which gets the parameters to the workspace as I want it to be) an then start the Simulation with sim(‘Gelenkmodell’) an error occurs.

Passing data from Mask to Block
I have a custom block ‘MyBlock’ in my custom Simulink library. Basically it’s clock and a Matlab function block ‘MyFunction’ afterwarts.
The mask of ‘MyBlock’ has a spinbox parameter ‘nValue’. Basing on ‘nValue’ I compute a matrix ‘myMatrix’, and this is a heavy computation but it can be put in Parameter Callback, since ‘myMatrix’ changes only if ‘nValue’ is changed. The block ‘MyFunction’ can performe the calculation using ‘myMatrix’ fast and easy.
The question is: how can I pass myMatrix to the ‘MyFunction’? It is not a mask parameter, so I can’t get assess to it…I have a custom block ‘MyBlock’ in my custom Simulink library. Basically it’s clock and a Matlab function block ‘MyFunction’ afterwarts.

Simscape IL actuator connecting port A and B using valve
The directional valve 304 is set to connect port 2 and 4 (port A and B of the piston). Now, when applying a force on the piston R, an error occurs. When connecting A and B directly (without valve 304) the piston moves back to cap C, as expected. Why does it not work with the valve though? There is a connection between 2 and 4, I checked, for a brief moment there is mass flow from port A to B, before the error pops up.The directional valve 304 is set to connect port 2 and 4 (port A and B of the piston).
