One-liner for if then [duplicate]

Answer 1

Try to avoid using if statements in matlab, and just convert your logic to (vector) math:

foo = 1 + (a <= b)

Edit:

For the more general case, of assigning 'r' or 'g', you can use:

col = {'r', 'g'};
foo = col(1 + (a > b));

So for example with an isGreen boolean you could do:

foo = col(1 + isGreen);

This could also be a boolean returning function

foo = col(1 + isGreen(a))
