Change While condition based on if statement

Question

0 个投票

Hi,

I would like make the following:

if PN == 1 || APN == 1
    Condition 1 (Time<10)
else
    Condition 2 (Vc>0)
end
While (Condition1/Condition2)
end

Is there a way to choose the condition for the while loop depends on the value I receive from the if statement?

Thank you.

It is possible to set this up yes, but your conditions are not in Matlab syntax so it is rather hard to see what exactly you are wanting to happen.

This is not elegant, but it achieves your goal:

while ((PN == 1 || APN == 1) && Time<10) || ...
        (~(PN == 1 || APN == 1) && Vc>0)
    %code
end

ben - I suppose you could use a function to evaluate your condition, and you would set the function based on the if/else from above. For example,

myConditionFunc = [];
if PN == 1 || APN == 2
    myConditionFunc = @(x,y)x < 10;
else
    myConditionFunc = @(x,y)y < 0;
end

So myConditionFunc takes two inputs which will be your Time and Vc. The while loop condition then looks like

 while myConditionFunc(Time,Vc)
    % something
 end

Presumably, within your while loop, the Time and Vc are updated based on some other criterion.
