Reference of all functions of Siglab - panel E functions

 
These functions are wrappers around standard ones to avoid imaginary results .
 

Buttons	Shortcut	Result and Explanation
		Acos(x) arccosinus x, -1<=x<=1 .
		Asin(x) arcsinus x, -1<=x<=1 .
		RLog(x) is neperian logarithm for x>0.
		Rlog10(x) is base 10 logarithm .
		20*Rlog10(signal).
erf		The error function : y = 2/sqrt(%PI) * integral from 0 to x of exp(-t^2) dt  .
erfc		The complementary error function : y = 2/sqrt(%PI) * integral from x to inf of exp(-t^2) dt = 1 - erf(x)  .
erfcx		The scaled complementary error function : y = exp(x^2) * erfc(x) ~ (1/sqrt(pi)) * 1/x for large x.
scilab		This is a recent addition. If you have a variable in scilab, you can type it there and it creates a signal for this variable. Let us have a try. Type "a=(sin((1:10000)*2*%pi/100)+(1:10000)/1000)';" in scilab command window. Then click on the scilab button and type a,"",1. A new signal appear in siglab that is directly taken from scilab. Then recoprocical operation is trivial in taking the data from the loM list of structures.
