Where is the problem in this if-else structure?
3 views (last 30 days)
This is an if-else structure of a larger problem. I have simplified it down to the numerals in work here, but can't figure out where lies the problem.
when I evaluate this simple if structure, the program effortlessly outputs a value of "w=1", (The program enters the structure.)
if (1 > 0)&(3 <= 4)
w = 1;
But when I evaluate the same above structure inside an if, else if combination the program won't enter in the "elseif structure" for some reason, and only outputs "m=0", whereas I should also get "w=1". What am I doing wrong?
if (4 <= 4)& (3 <= 4)
elseif (1 > 0)&(3 <= 4)
w = 1;
Matlab always evaluates:
(4 <= 4)& (3 <= 4)
equals to logical 1. Why won't it then enter inside the if, else-if structure?

"whereas I should also get "w=1"."   No it should not, because doc says "The statements execute only if previous expressions in the if...end block are false.". In your case a previous expression, (4 <= 4)& (3 <= 4), is true. Only the statements following the first expressions that is true will be executed.

because in your
cond1 and cond2 are nested, cond2 only happens if cond1 is false. Because in your example cond1 is 1, true, the if exits. It's the way it works.
or try a switch
