Max - what is infoRatioTargetReturn? Is this a function of that you have written or is it from somewhere else?

You are trying to call a function that is not in your current folder nor on your path.

It looks like this is the example you are trying to use:

openExample('finance/PortfolioOptimizationBenchmarkExample')

Note that the function called by this script is included in-file at the botton.

function [infoRatio,wts] = infoRatioTargetReturn(targetReturn,portObj)
% Calculate information ratio for a target-return portfolio along the
% efficient frontier
wts = estimateFrontierByReturn(portObj,targetReturn);
portRiskAct = estimatePortRisk(portObj,wts);
infoRatio = targetReturn/portRiskAct;
end

You would need to create an m-file function for this function if you want to run this example from the command window. Better to just open the live script example and run it in the editor.
