min Returns the smallest of a set of variables as in min(a;b;c;d)
ln Calculates the natural logarithm (base e) of x as in ln(x)
log10 Calculates the base 10 logarithm of x as in log10(x)
sin
Calculates sine as in sin(x)
sinh Calculates hyperbolic sine as in sinh(x)
sqrt Calculates square root as in sqrt(x)
sum Calculates the sum of multiple values as in sum(a;b;c;d)
tan Calculates tan as in tan(x)
tanh Calculates hyperbolic tan as in tanh(x)
Note:
Trigonometric functions (sin, cos…) use radians arguments, not degrees.
Special channel functions
slope Calculates the slope (or differential) of a channel as in slope(channel).
area Calculates area under the channel curve or partial integral (or area)
as in area(channel; t0; t1) where t0 and t1 are constants in seconds in the session. Can
also be used as in area(channel; t-10; t+10) to calculate running area (integral).
Note1:
The slope functions will only take a channel name as argument, not an evaluated function
as in slope(channel * x + y).
The automatic unit conversion operator can be applied though.
Note2:
Slope calculations are very sensitive to noise on the channel. To minimize noise it is better
to smooth the channel before applying the calculations. As a rule, smoothing of 0.25 to 1
second is enough in most cases (reasonably smooth data to begin with). Experiment with
the right smoothing value for your application.
