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...
