evalmf: Evaluate fuzzy membership function
In FuzzyR: Fuzzy Logic Toolkit for R

Description Usage Arguments Details Value Author(s) Examples

To obtain the corresponding membership grade(s) for given crsip input(s) x

1	evalmf(...)

...

For singleton fuzzification: x, mf.type, mf.params; x, mf.
Four additional parameters need to be used for non-singleton fuzzification: fuzzification.method, fuzzification.params, firing.method and input.range. See details below for more information.

x - the crisp input(s) on the universe of discourse for corresponding antecedent membership function
mf.type - The type of fuzzy membership function
mf.params - The parameters for the given type of membership function
mf - the membership function generated by genmf
fuzzification.method, fuzzification.params, firing.method and input.range - see addvar

Usage:

evalmf(x, mf.type, mf.params)
evalmf(x, mf)
evalmf(x, mf.type, mf.params, fuzzification.method, fuzzification.params, firing.method, input.range)
evalmf(x, mf, fuzzification.method, fuzzification.params, firing.method, input.range )

Membership grade(s)
