-==== startup.m ====
-When MATLAB starts, it looks for a pathdef.m file in its startup directory.
+==== Exiting loop (for / while -> pause) gracefully ====
+(i.e., without "ctrl-C" abort)
-Start up folder (in the icon | Properties | Start in ) (e.g. D:\Sources\MATLAB) allows controlling different paths and other settings via startup.m file placed in the folder, e.g.:
+For example, when paging thru trials:
+<code matlab>
+figure('Name','Plot trial','CurrentChar',' ');
+for k = 1:length(trial),
+...
+	drawnow; pause;
+	if get(gcf,'CurrentChar')=='q', % pressing "q" will exist the loop, make sure focus is on the figure!
+		break;
+	end
+	clf;
+end

+==== Finding indices between two vectors of start and end indices, using arrayfun ====
+Assume we have two vectors, repeated_segments_start_idx, and repeated_segments_end_idx, and we want to find all indices between each pair.
 <code matlab>
-disp('Welcome to physiology analysis...');
+idx = [repeated_segments_start_idx(segments2remove_idx):repeated_segments_end_idx(segments2remove_idx)] % DOES NOT WORK, OF COURSE!
-set_sources_path; % set additional paths dynamically, e.g.
-% p = genpath('D:\Sources\MATLAB'); addpath(p);
-cd('F:\Data');
+idx = cell2mat(arrayfun(@colon,repeated_segments_start_idx,repeated_segments_end_idx,'UniformOutput',false)); % WORKS!
-edit;
-EditorMacro('Alt-Control-h', @createHeaderComment_dag);
-dbstop if error
 </code>
+==== Maximize figure window ====
+<code matlab>set(gcf,'units','normalized','outerposition',[0 0 1 1]);</code>
+==== Plot an ''imagesc'' with transparent NaNs ====
+<code matlab>
+h = imagesc(X,Y,C);
+set(h,'alphadata',~isnan(C));
+</code>
+==== Shifting colormaps ====
+Sometimes the colormap plots are shifted after printing. To fix this:
+- in Adobe Illustrator, click on the colormap, release clipping mask, and go to "Object", "Rasterize", in the "Resolution" part click on the "Use Document Raster Effects Resolution".
+You have to do it for each of the colormaps.
