39	39	* `sign()` `dirac()` `theta()` denote the signum, Dirac delta and heaviside functions. Note: If the number field is complex or complex-rational, those functions are only defined if the imaginary part of the argument is zero.
40	40	* `atan2()` denotes the atan2 function. It takes two real arguments x and y separated by a semicolon: `atan2(x;y)`, e.g. atan2(-1; 1)
41		- * finally, `min()` `max()` compute the minimum or the maximum of an as input given matrix / row vector, either defined as a matrix / row vector identifier or directly (using the [python like syntax](/wiki/Matrix-Variables.md#2-python-like-syntax) ). E.g. `min(myMatrix)` where _myMatrix_ is a matrix identifier, `min([1;3;-2;5])`. Those two functions are not defined for non-real numbers.
