There are two 3X leveraged ETFs in relation to UNG, and those are UGAZ and DGAZ. They are the VelocityShares funds that apply 300% and -300% to the S&P GSCI Natural Gas Index Excess Return (SPGSNGP). ... DGAZ is the inverse, so as UNG increases 1%, DGAZ falls 3%.

Answered April 5, 2015. pinv() function in OCTAVE/MATLAB returns the Moore-Penrose pseudo inverse of matrix, whereas the inv() function returns the inverse of the matrix. Let A be an m*n matrix. B is said to be the generalized inverse of A if, ABA = A.

If the DDH problem is hard relative to G, then the El Gamal encryption scheme is CPA-secure. ... We prove that El Gamal scheme Π has indistinguishable encryptions in the presence of an eavesdropping and let Proposition 11.3 take it from there.

Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.

The inverse of a function f is a function g such that g(f(x)) = x. So if you have the function f(x) = ax2 + bx + c (a general quadratic function), then g(f(x)) must give you the original value x.

In the math example, the steps are to multiply by 8 and take the cube root. The inverse operations in reverse order are to cube and divide by 8. Take x, cube to get x3 and divide by 8 to get x3/8. This x3/8 is called the inverse function and is written as f-1 (x).

Any element in Z Matrix can never have a negative Real part. But the inverse of this matrix which is Y matrix has elements which have negative real parts. H Matrix since it specifies the relation between v ,i ,impedance, admittance it can have elements which has negative Real part.

IN GENERAL , has NO INVERSE , IF IT IS NOT A ONE-TO-ONE FUNCTION.,because only such functions are invertible. ⑵ BUT if a cubic functionis is of the following form/can be converted to the following form, it is invertible : (i) f(x)=(ax+b)³+c, a≠0 , b,c∈|R, with its natural domain, x∈|R or a reduced domain.

If you have a nice enough structure, every element (e.g. pxp) has an additive inverse, usually denoted by prefixing - (e.g. -pxp), such that sum of those two elements is the additive neutral element, usually denoted by 0. ... So pxp-pxp=0 by transitivity of equality.

Divide x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=ln(x)ln(3) f - 1 ( x ) = ln ( x ) ln ( 3 ) is the inverse of f(x)=3x f ( x ) = 3 x .

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.

A symmetric matrix is invertible if it is not singular ( determinant is not equal to 0 ).

An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing.

Exponentiation and log are inverse functions. Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x f - 1 ( x ) = 2 x is the inverse of f(x)=log2(x) f ( x ) = log 2 ( x ) .

g = finverse( f ) returns the inverse of function f , such that f(g(x)) = x . If f contains more than one variable, use the next syntax to specify the independent variable. g = finverse( f , var ) uses the symbolic variable var as the independent variable, such that f(g(var)) = var .

X = finv(P,V1,V2) computes the inverse of the F cdf with numerator degrees of freedom V1 and denominator degrees of freedom V2 for the corresponding probabilities in P . P , V1 , and V2 can be vectors, matrices, or multidimensional arrays that all have the same size.
