Function compare #

Compare two values. Returns 1 when x > y, -1 when x < y, and 0 when x == y.

x and y are considered equal when the relative difference between x and y is smaller than the configured epsilon. The function cannot be used to compare values smaller than approximately 2.22e-16.

For matrices, the function is evaluated element wise. Strings are compared by their numerical value.

Syntax #
