Can you put a switch statement within an IF statement?

I want two values to be set if two conditions are true. A and B are absolute decimal numbers. array(k,j+1) is either the value 12345 or a complex number with decimals. I tried:
if (A<B) && (array(k,j+1) == 12345)
B = A
C= k
end
Because this didn't work (not desired output), I tried an if statement within a switch statement:
switch array(k,j+1)
case 12345
if A<B
B=A
C=k
end
otherwise
;
end
This also didn't work (not desired output), so I tried:
if A < B
B=A
switch array(k,j+1)
case 12345
C= k
otherwise
;
end
end
It seems that none of these things give the desired output, has anyone and idea/suggestions?

all off them work but not as you expect them to
i suppose A and B are matrices...
check the output of A<B and when it is "true", this should solve your problem

The first one should work if A & B are scalars. Because they didn't it's possible that array or the 12345 number may be floating point, double numbers, NOT integers. If they're not pure integers, like int32 or uint16 or whatever, or at least doubles with integer values, then you need to read and understand the FAQ: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F
If A & B are arrays and you want to test that every single value of A is less than the corresponding B at that location, and array and 12345 might be some floating point numbers then you can do
if all(A<B) && abs(array(k, j+1) - 12345) < someSmallToleranceNumber
B = A
C = k
end
