Hi all I want to add a band of fluctuaci?n (exponential decreading) to a linear deacrecing values Imagine: I have a matrix like c(10,9,8,7,6,5,4,3,2,1) The thing is I want two new lines so that the m?ximum value of the new colum on the m?ximum is from 10% to 5% higher and the same lower for the m?nimum the final two matix will be something like c(10+0.10*10,9+0.089*9,8+0.075*8.....,1+0.05*1) c(10-0.10*10,9-0.09*9,8-0.075*8.....,1-0.05*1) What I?m looking for is a function tu calculate de "values, weights" so that including the 10% and 5% and the nunmber of decreasing values, in this case n=10, calculates de smotth weigths. I don?t know if I have expalined well so thar finally putting initial value final and periods I can find a matrix like g(0.1,0.89,0.79,0.075,...,0.05) Exists something like that?

I explain better: I have this percentage z<-1/(n*365) where n=20 so z is 0,000136986 Imagine: a matrix with length(n*365) so that matrix result is resultc( 1, 1-z result previous row-z result previous row-z .... 0) If I plot this is a linear decreasing line I want to plot an upper line wich is 10% higher tan resultc on the first values and then decreasing so that last value will be 0.05. the same in the lower, a line which values are at the beggining a 10% lower and smoothly dreasing values till the last will be 5% lower. Is it posible to make thins bands exponencially with a code? 2017-06-01 20:20 GMT+02:00 Pedro p?ramo <percentil101 at gmail.com>:> Hi all > > I want to add a band of fluctuaci?n (exponential decreading) to a linear > deacrecing values > > Imagine: I have a matrix like c(10,9,8,7,6,5,4,3,2,1) > > The thing is I want two new lines so that the m?ximum value of the new > colum on the m?ximum is from 10% to 5% higher and the same lower for the > m?nimum > > the final two matix will be something like > > c(10+0.10*10,9+0.089*9,8+0.075*8.....,1+0.05*1) > c(10-0.10*10,9-0.09*9,8-0.075*8.....,1-0.05*1) > > What I?m looking for is a function tu calculate de "values, weights" so > that including the 10% and 5% and the nunmber of decreasing values, in this > case n=10, calculates de smotth weigths. > > I don?t know if I have expalined well so thar finally putting initial > value final and periods I can find a matrix like > > g(0.1,0.89,0.79,0.075,...,0.05) > > Exists something like that? > >[[alternative HTML version deleted]]

That is not a matrix.
