Undefined function or variable 'getFISCod​eGeneratio​nData'

I am trying to perform a simulation which uses fuzzy approach, I created the fuzzy system using the fuzzy logic designer, and i'm using it in two places within a for loop which runs fro around 15k rounds, after applying the fuzzy logic the code only gives about 12 iterations per minute, So to increase the speed I read about ambedding the fuzzy code at " https://in.mathworks.com/help/fuzzy/generate-code-for-fuzzy-system-using-matlab-coder.html "

but when i use the command : fis = getFISCodeGenerationData(fisObject);

I get the error " Undefined function or variable 'getFISCodeGenerationData'" and

codegen('evaluatefis1','-args',{coder.Constant(fis),[0 0]},'-config:mex') gives an error of access denied, I am using windows 10 and Matlab 2018a.

Help would be greatly appreciated I dont want to sit at the PC for 15hrs straight for one run.

From the below documentation is see that the function "getFISCodeGenerationData" is supported from R2018b (release is mentioned at the bottom of the page):

The second error may be related to the first one or else you may be trying the codegen command in a un-writable directory.

I'll check this.

Thank you Darshan,

I downloaded the latest trial version an this error was solved, but once again as you mentioned codegen is trying to write in an un-writable directory:

codegen('evaluatefis1','-args',{coder.Constant(fis),[0 0]},'-config:mex')

on reading the help section for codegen we can use " -d DIR " to specify directory but this doesn't accepts any path I provide

This is the error:

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other

syntax error. To construct matrices, use brackets instead of parentheses.

This is the code I entered:

codegen('evaluatefis1','-args',{coder.Constant(fis),[0 0 0]},'-config:mex') -d K:\MATLABBB

[Darshan Ramakant Bhat]

Please try below way :

codegen('evaluatefis1','-args',{coder.Constant(fis),[0 0 0]},'-config:mex','-d','K:\MATLABBB')

The options should be inside the ()

Did you able to generated the code ? Please accept the answer if it was helpful to you :)

Hola Darshan, yo también tengo problemas con "Undefined function or variable 'getFISCodeGenerationData' para un sistema de lógica difusa. Por favor, podrías explicarme los pasos para superar este problema. Soy de Perú y este es mi correo: [e-mail]

Gracias de antemano

Es cuando uso "fis = getFISCodeGenerationData(fisObject)"

This worked like a charm thank you so much I was stuck on this for days.
