addsubplot

ADDSUBPLOT moves the existing axes to subplots and adds a new subplot

ADDSUBPLOT
ADDSUBPLOT(where)
ADDSUBPLOT(h,___)
ADDSUBPLOT(___,name,value,...)

ADDSUBPLOTS will check first if there are unused subplot positions in the
figure. If yes, a subplot will be created in that spot. Otherwise the
existing subplots will be rearranged by adding a new row or column and a
new subplot will be created.

parameters:
h = figure handle (default is current figure)
where = use 'right' or 'bottom' to specify where the new subplot should
be added. Use 'square' (default) to keep the subplots in a square
arrangement.
name,value,... = parameters will be passed to the subplot function
ax = axes handle to new subplot

example:
figure
for n = 1:25
addsubplot
plot(rand(5))
end
