Syntax

writeFIS(fis,fileName)
writeFIS(fis)
writeFIS(fis,fileName,"dialog")

Description

You can save a fuzzy inference system (FIS) in a .fis file using the writeFIS function. To load the saved file, use the readfis function.

Note

Do not manually edit the contents of a .fis file. Doing so can produce unexpected results when loading the file using readfis.

example

writeFIS(fis,fileName) saves the fuzzy inference system fis to the current working folder using file name fileName.

writeFIS(fis) opens a dialog box for saving a FIS. In this dialog box, specify the name and location of the .fis file.

writeFIS(fis,fileName,"dialog") opens a dialog box for saving a FIS, setting the name of the file in the dialog box to fileName. In the dialog box, specify the location for the file.

Create a fuzzy inference system, and add an input variable with membership functions.

fis = mamfis('Name','tipper');
fis = addInput(fis,[0 10],'Name','service');
fis = addMF(fis,'service','gaussmf',[1.5 0],'Name','poor');
fis = addMF(fis,'service','gaussmf',[1.5 5],'Name','good');
fis = addMF(fis,'service','gaussmf',[1.5 10],'Name','excellent');

Save the fuzzy system in the current working folder in the file myFile.fis.

writeFIS(fis,'myFile');
