while loop with a boolean expression

why my boolean expression is not working , is there any syntax error. here is my code :

v=false;

while ((i < N)&&(v==false)) if (condition) v=true; i=i+1; else i=i+1; end end

Don't even use v. Just break:

while (i < N) 
    if (condition) 
       break;
    end 
    i=i+1;
end

A few tips:

• v==false is rather awkward code, as the while operation requires a logical value: v is already a logical value, so instead of doing this round-about numeric comparison, why not just use the simplest form of ~v instead?
• Do not use i or j as loop variables names, as these are the names of the inbuilt imaginary unit.
• Using the else statement and repeating the code that increments the loop variable could be replaced by simply incrementing the variable once after the if statement.
• the if statement does nothing useful: why not just define v directly using condition?

Altogether we get this:

v = false;
while k<N && ~v
    v = ~condition;
    k = k+1;
end

which we can then simplify be noting that everywhere ~v is used can simply be condition instead:

condition = true;
while k<N && condition
    k = k+1;
end
