Hi
I was looking at on of the sample code in matlab webinars, I could not understand the use of ~ in the code below , as I understand that ~ (not) is a logical operator.
% Perform a parameter sweep to identify the best setting.
sh = nan(100,1);
for m = 2:100
[~,~,sh(m)] = leadlag(BundClose,1,m);
end
[~,mxInd] = max(sh);
Please help, thanks in advance.

When ~ appears in the left side of an assignment statement with multiple outputs, it means that that particular output should be discarded.
For example,
[~,mxInd] = max(sh);
is the same as
[TEMP,mxInd] = max(sh);
clear TEMP
This syntax has only been part of MATLAB since about R2009b or so.
