Hello,
Is it possible to continue a caller loop from the function called ?
Example :
The caller is :
for i =1:5
test(i)
end
And the function is :
function test(i)
if i == 5
evalin('caller','continue')
end
end
and the result is :
Error using test (line 3)
Error: A CONTINUE may only be used within a FOR or WHILE loop.
Error in Untitled3 (line 2)
test(i)

You can signal that using flags
for i =1:5
flag= test(i);
if(flag)
continue;
end
end
And the function is :
function flag = test(i)
if i == 5
flag = true;
else
flag = false;
end
end

Try just runing a for loop, and enter a break point at iteration 3
Now Try typing break or continue on command prompt, it will give error
Error: A BREAK statement appeared outside of a loop. Use RETURN instead.
because you are not inside for loop due to breakpoint
Similar is the issue with eval or evalin function as when the evaluate you expression, it is not inside the for loop
