I have seen video about edit a colormap https://www.mathworks.com/videos/interactively-editing-a-colormap-in-matlab-97147.html , but i don't know, how to save the setting after I edit values. Specific example ... I edit map on the top with the cursor of mouse (move positive and negative values to the center - zero). How can I get this setting always?

My suggestion would be to create an image, set it as you want, save the colormap and color axis limits to a mat file.
cmap = colormap(gca);
cl = caxis;
save cmap.mat cmap cl
Then, when you want to use the same colormap, load the mat file, and set the colormap and color axis limits to the values loaded in the mat file.

You appear to be trying to save the file to a location you do not have write permission. Try changing your current folder location.
