用subplot（）函数在同一窗口画出y=sinx,y=cosx,y=x平方,y=x立方

如何使用循环语句缩短程序
subplot(521);
plot(index,a1);
subplot(522);
plot(index,a2);
subplot(523);
plot(index,a3);
subplot(524);
plot(index,a4);
subplot(525);
plot(index,a5);
subplot(526);
plot(index,d1);
subplot(527);
plot(index,d2);
subplot(528);
plot(index,d3);
subplot(529);
plot(index,d4);
subplot(5,2,10);
plot(index,d5); 以上是程序的一部分,我想问下可不可以把这段程序用循环语句简练的表达出来,这样实在是太麻烦了,麻烦大神老师们给看看,跪谢!

SUBPLOT Create axes in tiled positions.
H = SUBPLOT(m,n,p),or SUBPLOT(mnp),breaks the Figure window
into an m-by-n matrix of small axes,selects the p-th axes for
for the current plot,and returns the axis handle.The axes
are counted along the top row of the Figure window,then the
second row,etc.For example,
SUBPLOT(2,1,1),PLOT(income)
SUBPLOT(2,1,2),PLOT(outgo)
plots income on the top half of the window and outgo on the
bottom half.If the CurrentAxes is nested in a uipanel the
panel is used as the parent for the subplot instead of the
current figure.
SUBPLOT(m,n,p),if the axis already exists,makes it current.
SUBPLOT(m,n,p,'replace'),if the axis already exists,deletes it and
creates a new axis.
SUBPLOT(m,n,p,'align') places the axes so that the plot boxes
are aligned instead of preventing the labels and ticks from
overlapping.
SUBPLOT(m,n,P),where P is a vector,specifies an axes position
that covers all the subplot positions listed in P.
SUBPLOT(H),where H is an axis handle,is another way of making
an axis current for subsequent plotting commands.
SUBPLOT('position',[left bottom width height]) creates an
axis at the specified position in normalized coordinates (in
in the range from 0.0 to 1.0).

load bust
X1=X;
map1=map;
subplot(131);image(X1);
colormap(map1);title('原始图像1');
axis square
load mask

end
