Hello everyone, I am working on a fruit classification problem using EfficientNet-B0, and I would appreciate some advice from anyone experienced with domain generalization / cross-dataset evaluation. I have a custom fruit dataset collected under real-world conditions, with different backgrounds,…
I am solving a nonlinear moonpool problem in MATLAB. The code can run either the linear pressure-drop term, the quadratic nonlinear term, or both. For the present test I use: % Change ONLY these two lines: linear = false; quadratic…
After initial download and install, I cannot get MATLAB 2025b to open. During startup the large blue MATLAB icon appears in front of white screen and then closes (crashes). What are the troubleshooting steps?After initial download and install, I cannot…

A while ago I have written a FEX submission that extends the capabilities of |find| to also work for 3D and up: < |findND|> (e.g. a syntax like |[x,y,z,val]=findND(A)|). I would like to be able to shadow the built-in function,…
If you place a road using the Road Plan Tool icon from the top menu in RoadRunner (see the reference page), a two-lane road with opposing traffic is created automatically. You can confirm this by selecting the Lane Tool icon and…
I have just updated from 2021a to 2025a and I cannot seem to figure out how to make my figures that I generate stop from being always docked in the figures window. I want each figure, from now on and…
With the following standard workflow to execute a RoadRunner simulation using the API command, I want to know the endpoint of the simulation. What the programming looks like for it? rrApp = roadrunner(projectFolder); rrApi = roadrunnerAPI(rrApp); openScene(rrApp, sceneFile); openScenario(rrApp, scenarioFile);…
I want to export the trajectory of the Sedan actor from a RoadRunner scenario by using the RoadRunner API. I used the following workflow: rrApp = roadrunner(projectFolder); rrApi = roadrunnerAPI(rrApp); openScene(rrApp, sceneFile); openScenario(rrApp, scenarioFile); rrSim = createSimulation(rrApp); set(rrSim, "MaxSimulationTime", 10); set(rrSim,…
I’m reading Ole Sigmund’s article called ‘A 99 line toplogy optimization code written in MATLAB’. I’m following the instruction to modify the topology matlab code to recreate the shape optimized with a radius. But my results ended up as follows:…
Hey all — I’m trying to simplify the matrix-scalar expression in the code below (treating the matrix as a whole, not expanding it). MATLAB won’t simplify it for some reason. Anyone know a quick fix? Should be pretty simple —…
Write a function called year2016 that returns a row-vector of struct-s whose elements correspond to the days of a month in 2016 as specified by the input argument. If the input is not an integer between 1 and 12, the…
Hi everyone I have a "simple" question that I am not sure how to do it in Matlab. I am new to Matlab. I want to mutliply large numbers in Excel (111111111 * 111111111) but it gives 12345678987654300 which is…
In the "Find Files" GUI there is a "Skip files over" field that sets an upper limit on the file size to include in the search. For me, it seems to be perpetually greyed out, and therefore cannot be modified.…

I cannot edit any values inside simulink using keyboard, it either doesnt respond or it spams a random key. i tried docking and un-docking windows but it didnt work. i am stuck with this forever i guess.I cannot edit any…
I have a simulink model running realtime that I was running using simulink 2023b on a speedgoat performance machine. I saw that 2026a had switched to a new RTOS so I updated my speedgoat to dual-boot and then compiled my…
In the deep learning pipeline, I want to use inverse operation on every page of 3D dlarray object. I have tried pageinv function. I find that the pageinv function is not supported for dlarray object while the pinv function is…
