I would like to get the fan1.zcos fuzzy logic demo module. Could anyone provide it to me? Thank you ---

I am not sure what you mean. The demo comes with the toolbox, right? The toolbox is here: > **[Scilab Module : Fuzzy Logic Toolbox](https://atoms.scilab.org/toolboxes/sciFLT/0.4.7)** > > sciFLT is a Fuzzy Logic Toolbox for scilab The toolbox is open source, available on Github, and the demos are here: > **[sciflt/demos at master · holgern/sciflt](https://github.com/holgern/sciflt/tree/master/demos)** > > sciFLT is a Fuzzy Logic Toolbox for scilab. Contribute to holgern/sciflt development by creating an account on GitHub. Is this what you were looking for? With kind regards, Claus ---

Hello Claus, Thank you for your reply. I had already downloaded those demo files. The one I am specifically reviewing is the fan1 demo. The demo files only have the fan.fls file from which I am able to build up a fan.xcos module using constant input blocks and a mux to combine them so there is only one input to the fls block in xcos. I am trying to read the output using the AFFICH.m module which apparently needs a CLOCK.m input as well, which I am dubious about. I don’t get consistent results, and I get the same result however I change my input. Is there a better way to view the output? Thank you for your assistance. Regards, Michael. ---

Hello Claus, Thank you for your reply. I had already downloaded those demo files. The one I am specifically reviewing is the fan1 demo. The demo files only have the fan1.fls file (there’s no fan1.xcos file) from which I am able to build up a fan1.xcos module using constant input blocks and a mux to combine them so there is only one input to the fls block in xcos. I am trying to read the output using the AFFICH.m module which apparently needs a CLOCK.m input as well, which I am dubious about. I get the same result however I change my input values of temperature and humidity.. Is there a better way to view the output? I am able to execute the flt\_fan1test.sce demo module in Xcos which produces the surface speed result for a complete range of temperatures and humidities. Trying to execute the flt\_fan1test.sce demo for just one temperature input and one humidity input, in the scilab console, gives an error message. Thank you for your assistance. Regards, Michael. ---

Hello Claus, If I input the temperature and humidity constants as vectors of shape [1,1], I think I am getting my xcos module to work! I need to input the values to the fan1.fls module as a vector of shape [2,1]. Thank you for your assistance. Regards, Michael ---
