Restart iteration in a for loop when an error is thrown

function my_outerspace_loop(maxtries=100)

    i = 1
    result = nothing
    function my_inner_loop(max)
        # global i
        while i < maxtries
            @show i
            try
                X=rand(100,100)
                X[1,1] < 0.1 || throw()
                X2=transpose(X)*X
                result = tr(inv(X2))
                break
            catch
                println("Trying again...")
                i += 1
                return my_inner_loop(max)
            end
       end
       return (result, i) # or 0 or whatever makes sense
    end

    my_inner_loop(maxtries)
end

In this case you would call my_outerspace_loop(n) where n is the maximum number of times you want to allow your algorithm to try to find an appropriate solution. You do not call my_inner_loop directly.

Is that what you meant by “how to call”?
