I need to transform the elements of a vector by a logistic function into a vector with elements with values between 0 and 1. I have tried:
S1=(1/(1 + exp(1).^(-1*Stemp)))
S1 and Stemp are vectors containing the same elements.
But get the error message:
Error in Fuzzylogic_cognitive_map (line 13) S1=(1/(1 + exp(1).^(-1*Stemp)))

or simply (with Grzegorz correction) S1=(1./(1 + exp(-Stemp)))

Matrix dimensions must agree. Add dot before division ( / ):
S1=(1./(1 + exp(1).^(-1*Stemp)))
