MATLAB: What effects are caused by usage of Boxes to graphically organize the chart in Stateflow

stateflow

The documentation of Stateflow Boxes reads as follows:

"You use boxes to graphically organize your diagram. Beyond this organizational use, boxes contribute little to how Stateflow diagrams execute."

I would like to know more about this feature.

This enhancement has been incorporated in Release 2008a (R2008a).

Using Boxes in your Stateflow Chart also affects visibility of functions. If you define a function in a Box, then this function is only visible to States within the same Box unless you call the function using dot notation. For example, use NameOfBox.NameOfFunction() instead of just Function() to call the function.

Stateflow documentation was enhanced in R2008a to provide more information about boxes. See "Using Boxes to Extend Charts".

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

MATLAB: Alternatives to substr without Stateflow

char arrays support indexing. Also, string is the name of MATLAB built-in function, so I named the name of the variable to 'str'

str = "This should really be in the MatLab core!";
%convert to character array
b = char(str); % you can simply use char()
ba = length(b);
%get index of "in the"
k = strfind(b,"in the");
stringbuilder = b(k:end);
stringbuilder = string(stringbuilder); % convert back to string

Result

>> stringbuilder
stringbuilder = 
    "in the MatLab core!"
