Hi,
I have a standalone application from Matlab code to Raspberry PI 4B (target hardware is the Raspberry). My question is that can I save a figure (plot) with standalone application to Raspberry? (I can use fprintf command to save text files to Raspberry, but I don't know that it is possible to save figures like text file. I have a lot of data and I'd like to plot them already on the Raspberry.)
Thanks,
Roland

Hello Nagy,
The "plot" function in MATLAB is not codegen capable and so you cannot use it directly for deployment.
A workaround you can try:
  1. Save your data to a binary file withn the SD card of Raspberry Pi (please refer fwrite )
  2. Transfer the binary file to MATALB and read the data from the binary file (please refer fread )
  3. You can plot the required data in MATLAB
Hope this helps,
Reeno

Hi,
Ok, my second think was this, I just wondered if there was another solution. In this case, I will do this.
Thanks,
