trying to make a graph of each iteration in my while loop

i use a pause(0.5) to get a graph out which works however once i pause it pulls me out of the while loop

function [c]= bisection(a,A,B,varargin)
nvarargs =length(varargin);
if nvarargs>3
    error('requires at most 3 optional inputs');
end 
%set defaults for optional inputs
optargs = {0.000001 50 0};
optargs(1:nvarargs) = varargin;
[tol,maxiter,plt] = optargs{:};

if a(A)*a(B)>0
    error('must choose new bracket')
end 
i=0;
while i~=maxiter
    i=i+1 
     c=(A+B)/2
if i>1
    ea=abs(c-X);
    if abs(a(c))<=tol | ea<= tol
       i=maxiter;
    elseif i==maxiter & (abs(a(c))>tol | ea >tol)
         error('root within given tolerance not found within maxiterations')
    end
end
%     if i>1 & plt==1
%         pause(0.5)
%         x_ax=[A,B,c]
%         Y_ax=[a(A),a(B),a(c)]
%         plot(x_ax,Y_ax)
%         
%     end
    
  if a(A)*a(c)<0
    B=c;
else
    A=c;
end 
X=c;
a(c)

end
end

i commented the relevant bits of the function

Use pause function as

while condition 
...
...
if condition 
 ...
 plot(...)
end
...
...
pause(0.5);
end % while loop

[tyler hollings]

actually it gives me all the plots but just saves the last one

[per isakson]

I miss the command

hold on

[tyler hollings]

that gives me all the points of the graph, how do i make it so its all seperate graphs?

[Walter Roberson]

subplot() or figure() or use tiledlayout()

[per isakson]

... and replacing

plot(x_ax,Y_ax)     % plots to the current axes, i.e. overwrites

by

figure, plot(axes,x_ax,Y_ax)    % creates a new figure for every plot

will give you a bunch of figures, each with one diagram

You may use saveas function in MATLAB to save plots in each iteration of the loop.

Example :

for k=1:5
 h=figure
 plot(...)
 saveas(h,sprintf('FIG%d.png',k)); % will create FIG1, FIG2,...
end
