A collection of personal matlab utility functions written over the years (2001-present).
The functions that I find myself using most often and unable to live without are jisubplot/nextplot, gridx/gridy/patchx, jisuptitle, jicolorbar, nudgeAxis, insetAxis, hideAxisLabels, timestamp, the colormaps, orthoMontage, parameter, structure and string utilities, hilbert analysis, jnearest. May you find something useful here.
I suggest you clone ji_utils from github and then add ji_utils to your path. If you download from the matlab file exchange, rename the download from github_repo to ji_utils...
blockclose - blockclose prevent a figure from being closed by the 'close' command combineFigs - combineFigs Combine a set of figure windows into a single figure expmulti - expmulti Export all plots prepared with jisubplot/nextplot. ff - flipfig (ff) flip through a set of figures numScreens - numScreens return the number of displays attached to this computer orthoMontage - orthoMontage make an orthogonal montage of a 3-d figure
jisubplot suite (see file exchange; predates tiledlayout by 15 years and offers a few additional benefits including figure sizing, tiling by row or column, skipping and printing axis labels only at endges of figure...
currentplotis - currentplotis Test if current plot pane is at a special location (e.g. row end, etc) jisubplot - Set up a figure for multi-pane plotting. Used with NEXTPLOT. nextplot - Advance to next plotting pane in figure set up with JISUBPLOT.

baroutline - baroutline Draw outline of a bar plot (useful for histograms) histoutline - histoutline Draw histogram outline jierrorbar - Error bar plot. Fixed ERRORBAR to enable proper legends (JRI 12/01) jihist - jihist more powerful histogram analysis/plotting plotDashedError - plotDashedError Plot curve with error range dashed above and below plotDisjoint - plotDisjoint Plot disjoint segments of a curve plotMeanMarker - plotMeanMarker show triangular marker marking the mean plotShadedError - plotShadedError Plot curve with error range shaded underneath sidehist - histoutline Draw histogram in outline form vertically xyerrorbar - xyerrorbar plot points with x and y errorbars
PLOT ADORNMENTS AND MODIFICATION
cbal - cbal balance clim of plot (center on 0) gridx - gridx Plot vertical x grid lines gridy - gridy Plot horizontal y grid lines hideAxisLabels - Hide axis text labels (but not ticks) insetAxes - insetAxes Flexible creation of inset plots. Can add an inset version of one axis onto another. jicolorbar - Same as COLORBAR, but does not resize current axis. (JRI) jisuptitle - Puts a title above all subplots. Does not resize axes (unlike suptitle). jititle - jititle JRI's version of TITLE with control of font size and location jititlesub - Add a title and subtitle to current axis jixlabel - jixlabel JRI's version of XLABEL with control of fontsize. jiylabel - jiylabel JRI's version of YLABEL with control of fontsize. lllabel - Put a text label in lower left corner of a plot nudgeAxis - nudgeAxis Shift axis position patchx - patchx plot shaded patches on plot plotgrid - plotGrid Flexible plotting of grid lines timestamp - Timestamp the current figure. ullabel - Put a text label in upper left corner of a plot xbal - xbal balance xlim of plot xticklabel - xticklabel replacement for setting xticklabels directly, allowing tex strings xyline - xyline draw line x=y on current figure ybal - ybal balance ylim of plot ylimall - ylimall make ylim of all axes in a figure the same
greenred - Colormap: red thru black thru green, for distinguishing pos & minus hotcold - Colormap: hot thru black thru cool blues, nice for distinguishing pos & minus hotwhitecold - HOTCOLD Colormap: hot thru black thru cool blues, nice for distinguishing pos & minus pastelmap - Modified Brewer pastel 1 colormap for GUI cell backgrounds redblue - Colormap: blue thru black thru red, for distinguishing pos & minus redgreen - REDGREEN Colormap: green thru black thru red, for distinguishing pos & minus redwhiteblue - Colormap: blue thru white thru red, for distinguishing pos & minus redwhitegreen - REDWHITEGREEN Colormap: green thru white thru red, for distinguishing pos & minus revmap - revmap reverse colormap
INTERACTING WITH PLOTS
