MATLAB中次刻度个数的设置方法

ax.XAxis.MinorTick = 'on'; 只能打开次刻度，而不能设置个数，下面是个小函数用来指定每个主刻度之间的次刻度的个数

% dxMINORXY(nx,ny)

function dxMINORXY(nx,ny)

% 说明 dxMINORXY(nx,ny)

% 输入：nx、ny分别为x、y轴两个主刻度之间次刻度的个数。

ax = gca;

%XY limit value

xlim = ax.XLim;

ylim = ax.YLim;

%XY tick value

xtick = ax.XTick;

ytick = ax.YTick;

%XY dtick

dxtick = (xtick(2) - xtick(1));

dytick = (ytick(2) - ytick(1));

%XY minortick interval

dmx = dxtick/nx;

dmy = dytick/ny;

  %XY minortick value

ax.XAxis.MinorTick = 'on';

ax.XAxis.MinorTickValues = ...

[(xtick(1)-dmx):-dmx :(xlim(1)-dmx),...

xtick(1) : dmx: xtick(end),...

(xtick(end)+dmx): dmx:(xlim(2)+dmx)];

ax.YAxis.MinorTick = 'on';

ax.YAxis.MinorTickValues = ...

[(ytick(1)-dmy) :-dmy:(ylim(1)-dmy),...

ytick(1) : dmy: ytick(end),...

(ytick(end)+dmy): dmy:(ylim(2)+dmy)];

% first element is for 2d fig ticklength

ax.TickLength = [0.015,0.05];

end
