How to check if several variables are not equal ?

Hello How to check if several variables are not equal ? for example:

for i=1:row1
    for j=1:row1
        for k=1:row1
            for ii=1:row1
                for jj=1:row1
                    for kk=1:row1
So I want to check that they are all not equal, in case they are different do the following:... so any help how to do this ?
Thanks

use isequal. It checks all the inputs are equal and if yes, it returns 1. Use ~ if you want only the else case.

 if isequal(var1,var2,var3,...)
   ...
 else 
   ...

But so many for loops, explain your real problem, it may have a simpler approach.

Okay will try it.

I am trying to get data from wsdream dataset which is a web services dataset.

Given that I have 140 service providers, where each may provide some components from a set of 4500 components. So How to find 6 providers which provide the same 3 components ?

Thanks

Quite vague and I can only give you some hints rather than creating some dummy data to show you an example.

1. Store your data in a table.
2. Filter data based on components.
3. Use something like ismember across the result you get in the above step to find the common provider across 3 components.
