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...
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.

How to get elements with multiple classes
...ast one class)
var list = document.querySelectorAll(".class1,.class2");
XOR (one class but not the other)
var list = document.querySelectorAll(".class1:not(.class2),.class2:not(.class1)");

subtle differences between JavaScript and Lua [closed]
...xample, if foo ~= 20 then ... end.
Lua 5.3 and up use ~ for binary bitwise XOR, whereas JS uses ^.
In Lua, any type of value (except nil and NaN) can be used to index a table. In JavaScript, all non-string types (except Symbol) are converted to strings before being used to index an object. For exam...
String comparison in Python: is vs. == [duplicate]
...If you have bool_a == 3 and bool_b == 4, then bool_a != bool_b, but bool_a xor bool_b is false (because both terms are true).
