Hello
I want the conditions of an issue to be graphically displayed at each step of the program. For example, in the case of a River crossing puzzle, I want to show which people (variables) are on which side of the river at each step.
Thanks

What data you have? You can display that using plot with some markers color depending on people are on which side.

In this case we have eight people
I considered each side an 1*8 representation
We move people according to the input received from the user
For example, if the first 2 people go from left to right, the situation will be left
001111111
The position will be on the right
11000000
How can I graphically show this situation now?

not sure this is what you had in mind ...
%Environment
envSize=4;
figure;
x=-envSize:0.1:envSize;
y=.5*sin(x);
plot(y,x,'lineWidth',10)
axis([-envSize envSize -envSize envSize]);
hold on;
%Input
left=[0 0 1 1 1 1 1];
right= [1 1 0 0 0 0 0 0];
% number of ppl
nL=sum(left);
nR=sum(right);
%random position for ppl
maxX=envSize-1;
minX=2*max(y);
maxY=envSize-1;
minY=-(envSize-1);
pL = [-(minX + (maxX-minX) .* rand(nL,1)), (minY + (maxY-minY) .* rand(nL,1))]
pR = [(minX + (maxX-minX) .* rand(nR,1)) , (minY + (maxY-minY) .* rand(nR,1))]
% plot
scatter(pL(:,1),pL(:,2),'filled','SizeData',200)
alpha(.5)
scatter(pR(:,1),pR(:,2),'filled','SizeData',200)
alpha(.5)
the output looks like this

That's it
Thank you very much for your kindness

Sorry, I just realized... this just control the shape of the plot but does not mean that if a circle person moved from the left to the right that person will remain a circle.
If you want to assosiated the shape with the person... try this
shapes=['o' '+' 's' 'd' '.' '>' 'x' '*' '^'];
leftcounter=1;
rightcounter=1;
for i=1:1:nL+nR
if left(i) ==1
scatter(pL(leftcounter,1),pL(leftcounter,2),shapes(i),'SizeData',200)
alpha(.5)
leftcounter=leftcounter+1;
else
scatter(pR(rightcounter,1),pR(rightcounter,2),shapes(i),'SizeData',200)
alpha(.5)
rightcounter=rightcounter+1;
end
end
hope it helps.
