xtick.m

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the p

function[]=xtick(i1,i2)
%XTICK  Set locations of x-axis tick marks.
%
%   XTICK(DX) or XTICK DX where DX is a number uses DX as the interval
%   between successive x-tick marks, with the endpoints being the
%   left- and right-hand axes limits, and applies this to the current
%   axis.
%
%   XTICK(DX) where DX is an array sets the 'xtick' property of the
%   current axis to DX.
%
%   XTICK(H,DX) applies the change to axes H. 
%
