Syntax

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

Description

writeFIS(fis,fileName) saves the fuzzy inference system fis to the current working folder using file name fileName. You can save files to either a FIS file (*.fis) or a MAT file (*.mat).

example

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

writeFIS(fis,fileName,"dialog") opens a dialog box for saving a FIS, setting the name of the FIS or MAT 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.

writeFIS(fis,fis.Name);

Input Arguments

collapse all

Fuzzy inference system, specified as one of these objects:

  • mamfis — Mamdani fuzzy inference system

  • sugfis — Sugeno fuzzy inference system

  • mamfistype2 — Type-2 Mamdani fuzzy inference system

  • sugfistype2 — Type-2 Sugeno fuzzy inference system

  • fistree — FIS tree (since R2024b)

File name, specified as a string or character vector. You can save your fuzzy system using one of the following file types.

  • FIS file (*.fis) — Save a mamfis, sugfis, mamfistype2, or sugfistype2 object.

  • MAT file (*.mat) — Save a mamfis, sugfis, mamfistype2, sugfistype2, or fistree object. (since R2024b)

If you do not specify a file extension, writeFIS adds the .mat extension when fis is a fistree object or the .fis extension for all other FIS objects.

Note

writeFIS changes the name of the saved FIS to match the specified file name.

Tips

  • Do not manually edit the contents of a FIS file. Doing so can produce unexpected results when loading the file using a function, such as readfis and getCodeGenerationData, or an app, such as Fuzzy Logic Designer.
