Running a function of 2 variables

I am having trouble running this command:

cr = [0:.1:1];
cr = logical(cr);
wn = [0:.1:1];
wn = logical(wn);
amp(cr,wn) = sqrt(1-2.*cr.*(1-cos(pi.*wn)).*(1-cr))

I get this error:

Subscripted assignment dimension mismatch.

Error in FundamentalsHW4 (line 6) amp(cr,wn) = sqrt(1-2.*cr.*(1-cos(pi.*wn)).*(1-cr))

Any help?

The best way for you to find what is wrong is to step through your code with the debugger.

Your code makes no sense, and you would have seen that immediately if you'd gone through the debugger. Why are you converting cr and wn to logical? Both of them end up as an array of 0 and 1 with only the first element as 0.

If you need more help, you would be better off explaining what you are trying to do rather than asking us to correct code that may not even be the solution to what you want.

cr = [0:.1:1];
wn = [0:.1:1];
f=@(cr,wn) sqrt(1-2.*cr.*(1-cos(pi.*wn)).*(1-cr))

amp=bsxfun(f,cr',wn)

I think that's what you want to do.
