How to toggle a boolean?
...ing converted to a number (that is either 0 or 1), you can use the Bitwise XOR Assignment Operator. Like so:
bool ^= true; //- toggle value.
This is especially good if you use long, descriptive boolean names, EG:
var inDynamicEditMode = true; // Value is: true (boolean)
inDynamicEditMod...

How can I apply a function to every row/column of a matrix in MATLAB?
...tors — <, <=, >, >=, ==, ~=
Logical operators — &, |, xor
Bit-wise functions — bitand, bitor, bitxor
Elementary math functions — max, min, mod, rem, hypot, atan2, atan2d
For example, you can calculate the mean of each column in a matrix A,
and then subtract the vec...

...ilable: isShut==false && isLocked==true. Because the types I have selected as my representation admit this state, I must expend mental effort to ensure that the class never gets into this state (perhaps by explicitly coding an invariant). In contrast, if I were using a language with algebr...

What about other operations, like logical_xor? Again, same deal… except that in this case there is no all/any-type function that applies. (What would you call it? odd?)

Why is a boolean 1 byte and not 1 bit of size?
... Not sure I would agree that bitwise operations are slow. ands, nots, xors etc are very fast. It is typically the implementation of the bitwise operations that are slow. At the machine level they are quite fast. Branching... now that is slow.
