mf2mf

(Removed) Translate parameters between membership functions

collapse all in page

    mf2mf has been removed. Convert membership functions using dot notation on fismf objects instead. For more information, see Version History.

    Syntax

    outParams = mf2mf(inParams,inType,outType)

    Description

    outParams = mf2mf(inParams,inType,outType) converts the parameters for one type of membership function into those of another membership function.

    Occasionally this translation results in lost information, so that if the output parameters are translated back into the original membership function type, the transformed membership function does not look the same as the original function.

    example

    Examples

    collapse all

    Create parameters for a generalized bell-shaped membership function, then convert them to parameters for a triangular membership function. Plot both functions to compare.

    x = 0:0.1:5;
mf1 = [1 2 3];
mf2 = mf2mf(mf1,'gbellmf','trimf');
plot(x,gbellmf(x,mf1),x,trimf(x,mf2))
legend('Generalized bell-shaped','Triangle-shaped','Location','South')
ylim([-0.05 1.05])

    The red triangular membership function plotted with the blue generalized bell-shaped membership function into which it was converted.
