Unrecognized function of variable 'R'.

Hi,

I am getting this messege "Unrecognized function of variable 'R'" though I have the variable in the workspace as you can see.

Thanks.

Functions have their own workspace, that's the whole points of function. If the function needs R and C, they need to be inputs to the function:

function H = myfunction(f, R, C)  %how about a better name for the function? One that actually describes what it does
    %..
end

which you call with:

>> myfunction(0:100, R, C)

Note that [0:100] is just a more complicated way of just writing 0:100. It's also marginally slower, since [] is a function call (to horzcat), which in this case does nothing.
