How can I use this code to assign the parameters of membershi function ‘mf’ of 1 and 2 to vector VParam using for loop. I tried but it gives only one mf parameters.

VParam=getfis(x,’input’,1,’mf’,1,’params’);

Hey Doug, I really liked the video and the job ur doing here. May I as well bring forward my query, as another novice in Matlab.
I need to store output of a function:
[x, y]=myfunc(imagefile), from a no. of (144) image pairs (each pair with members 1 & 2) from a directory.
they are .tif images; member1 filenames are ‘*0(.tif)’ and member2 filenames are as ‘*1.tif’. I need the store all outputs of member1 files in matrix(/array) A, and the others in B (say).
Also need to know if this’s better off as a subfunction of myfunc,or as a script in the same directory. Please help.Thanks a lot.

@ Majj

Probably store in a matrix:

for r = 1: 10;
 for c = 1: 10;
   m(r,c) = rand;
 end
end

Hi,
I’ve created a function with one input and three output.
Example:

function [out1 out2 out3] = F(input)

Then I’ve used the output in some file.m, which passes them as single values. My problem is that; I need to save all the output for each iteration number “say (i=1:100)” as a vector.
How do I do that; Note that when I’ve used global out1…out3 it keeps over write the values, and saved only the last value at the end of the loop.

Thanks
