REF

Peakf(channel, low, high)

returns peak frequency (highest amplitude) from FFT in a

band for a channel. E.g. Modf(2, 4, 6) returns the peak

frequency in channel 2 in band from 4 Hz to 6 Hz

Special Built-in Constants:

Schumann, SCH

Schumann Frequency = 7.81

PHI, GOLDEN, GM

Golden Mean = 1.618

PI = 3.14159

Standard Operators: Note: all arguments and parameters are treated as double precision floating point values

+ - * /

add, subtract, multiply, divide

modulus returns the remainder after an integer division

power: y = x ^ 2

()

parenthetical gropuing, unlimited, e.g. (2 + BETA) /

THETA

;

semicolon, needed at end of each equation in formula

comment, single line

/*…*/

comment, multiple lines

Priority of Operators:

()

highest

-x (unary minus)

next (e.g. y=-x^2, the ^ occurs before - )

*/^

lowest
