Error while using fuzzy logic command-evalfis
显示 更早的评论
On using the following command
FIS = readfis('fuzzy.fis');
FIS.input.range = pmax;
[Y,IRR,ORR,ARR]=evalfis(X,FIS);% X and Y are row matrices
The error looks like ??? Error using ==> evalfismex Calloc error in fisCreateMatrix!
Error in ==> evalfis at 84 [output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);
What may be the possible reason of this error and how can I remove it?

"Calloc error" in fuzzy logic appears when fuzzy rules are not set or any of fis structure field is empty. Check the fuzzy fis structure none of its field should be empty. example:
name: 'fuzzy_ex'
type: 'mamdani'
andMethod: 'min'
orMethod: 'max'
defuzzMethod: 'centroid'
impMethod: 'min'
aggMethod: 'max'
input: [1x3 struct]
output: [1x1 struct]
rule: [1x27 struct]

I would like to evalute not only a variable but a fuzzy set ("observation") it is possible ?

one possibility of this error is that..... after defining rules matrix you have not added rules to the FIS.... which is done using
a=addrule(a,ruleList);
where a is any FIS ruleList is rule matrix

"Calloc error" appears only, if the memory is exhausted. Check this by:
feature memstats
