- Antonio (9 days 22 hours ago): Note Intel’s MKL implementations of BLAS/LAPACK are already multi-threaded, so it is likely that you won’t achieve a vast improvement (the overall performance could even...
- Testing 123 (247 days 13 hours ago): The mexCallMATLAB function raises interesting possibilities for parallelization. I spent a few hours (days…) writing a mexFunction that mimics the functionality of...
- Andrés Aguilar (386 days 12 hours ago): Hello, has anyone tried to change the language of the DateComboBox? For example English -> French ————&# 8212;—- January -> Janvier April...
- Yair Altman (678 days 15 hours ago): You didn’t say what code you were trying to run and what exactly didn’t work for you, so I cannot help you. In general I can say that the code still works ok on...
- Nicholas (680 days 13 hours ago): It has come to my attention that in R2022a the content for HtmlText and CurrentLocation cannot be set for an HTMLBrowserPanel object. This can be easily demonstrated in R2022a with...
- bryan taylor (681 days 19 hours ago): I’m using matlab r2021a. The command above don’t seem to work. The commands run without error but the changes do no effect the text box.
- Yair Altman (698 days 21 hours ago): @Mitchell – in most cases the user wants a single string identifier for the computer, that uniquely identifies it with a distinct fingerprint that is different from any other...
- Mitchell (699 days 5 hours ago): Great post! I’m not very familiar with the network interfaces being referenced here, but it seems like the java-based cross-platform method concatenates all network...
- Eric (747 days 18 hours ago): this save me a lot of time, thank you very much!
- Yair Altman (1069 days 14 hours ago): You forgot to wait for the figure and the axes to fully render. After a pause and drawnow the code works ok (at least in R2021a).
- Anton Semechko (1069 days 14 hours ago): Hi, Yair, Do you know why is it impossible to add listeners to any of the uiobjects in UIFigure? And is there some way to work around this limitation? For example:...
- Davide Coluzzi (1104 days 13 hours ago): Hello, I have just found out this website and the book, they are great! Many thanks for this. I am developing a GUI in Matlab and I added a uiimage to receive info, so that...
- Yair Altman (1221 days 19 hours ago): drawnow is the entry function to Matlab graphics updates, which chains numerous internal drawing/painting calls, as well as associated callbacks (internal and user-defined)....
- Ondrej (1221 days 20 hours ago): Hi Yair, I have a slightly off-topic question. I am using Matlab 2017a and when using drawnow to refresh the graphics I noticed in the profiler (with -memory option on) this: Code...
