matlab中调整subplot各子图间间隔

 

python中可以用plt.subplots_adjust(wspace=0, hspace=0)函数来调整subplot中各子图间间隔

matlab中没有专门的函数用来调整subplot中各子图间间隔，但是在网上找到一个类似函数，

[ha, pos] = tight_subplot(Nh, Nw, [gap_h gap_w], [lower upper], [left right])

Nh：子图行数；
Nw：子图列数；
[gap_h gap_w]：子图的上下间距和左右间距；
[lower upper]：图上下边框宽度；
[left right]：图左右边框宽度；
ha：生成画布后，用来控制在第几个画布中作图

demo：

clear
clc

x = -10:0.1:10;
len = length(x);
y1 =zeros(6, len);
y2 =zeros(6, len);

for i=1:6
    y1(i, :) = sin(x)*i+i;
    y2(i, :) = cos(x)*i+i;
end
figure;
[ha, pos] = tight_subplot(3,2,[.05 .1],[.1 .1],[.1 .05]);
for i=1:6
    myxlabel = sprintf('xlabel %.2f', i);
    myylabel = sprintf('ylabel %.2f', i);
    mylegend1 = sprintf('sin %d', i);
    mylegend2 = sprintf('cos %d', i);
    axes(ha(i)); plot(x, y1(i, :), 'r', x, y2(i, :), 'b'); 
    xlabel(myxlabel); ylabel(myylabel); legend(mylegend1, mylegend2); grid on;
end

set(ha(1:4),'XTickLabel',''); 
% set([ha(2), ha(4), ha(6)],'YTickLabel','');

 

function [ha, pos] = tight_subplot(Nh, Nw, gap, marg_h, marg_w)
% tight_subplot creates "subplot" axes with adjustable gaps and margins
%
% [ha, pos] = tight_subplot(Nh, Nw, gap, marg_h, marg_w)
%
%   in:  Nh      number of axes in hight (vertical direction)
%        Nw      number of axes in width (horizontaldirection)
%        gap     gaps between the axes in normalized units (0...1)
%                   or [gap_h gap_w] for different gaps in height and width 
%        marg_h  margins in height in normalized units (0...1)
%                   or [lower upper] for different lower and upper margins 
%        marg_w  margins in width in normalized units (0...1)
%                   or [left right] for different left and right margins 
%
%  out:  ha     array of handles of the axes objects
%                   starting from upper left corner, going row-wise as in
%                   subplot
%        pos    positions of the axes objects
%
%  Example: ha = tight_subplot(3,2,[.01 .03],[.1 .01],[.01 .01])
%           for ii = 1:6; axes(ha(ii)); plot(randn(10,ii)); end
%           set(ha(1:4),'XTickLabel',''); set(ha,'YTickLabel','')
