I'm trying to save the current plot as .jpg. The code is the following :
filePath = 'C:\Users\leo-9\Desktop\roba pc nuovo\dottorato\Food network\plots\';
addpath(filePath);
name = strcat(filePath,plot_name,'.jpg');%num2str(itt)
%name = strcat('Figures_v2023\Stats\','Fig_Stats_',items_veg_name(stepp) );
saveas(gcf,name);
The error reported is the following :
Error using fopen
Unable to find file. Ensure file exists and path is valid.
Error in matlab.graphics.internal.name (line 94)
fidread = fopen(pj.FileName,'r');
Error in print (line 71)
pj = matlab.graphics.internal.name( pj );
Error in saveas (line 181)
print( h, name, ['-d' dev{i}] )
Error in BPR_plot_stats (line 41)
saveas(gcf,name);
Can you help me please?

You should use FULLFILE, just as Dyuman Joshi correctly recommended.
Also: avoid polluting the MATLAB seach path with folders of data files. In other words, get rid of ADDPATH.

Based on the code and the error message, it appears that the provided path may be incorrect, or you may not have the necessary permissions to write to the desired folder.
Another approach you might consider is using the “fullfile” function in MATLAB. This function helps generate the path string based on the platform (e.g., Windows or UNIX), ensuring compatibility.
Here, I have provided the updated code using the “fullfile” function:
filePath = <BASE PATH>;
name = fullfile(filePath,'xyz.jpg');
saveas(gcf,name);
You can find more information on using the “fullfile” function in the following documentation:
