Hi all,
Is it possible to use dot indexing in a function handle? Or at least ignore an output?
Please look at the code below.
clear
clc
close
format shortG
P = 100;
vel = 1.5066e+03;
omegab = 0;
L = 30480;
E = 200000;
I = 1.6253e6;
b = 2438;
h = 20;
A = b * h;
rho = 7.8E-9;
jmax = 5;
varMean = [P vel];
varStd = abs([0.15 0.15] .* varMean);
varDist = ["normal","normal"];
g = @(X) 1.76 - beamUnderMovingLoad(X(1),X(2),L,E,I,omegab,rho,A,jmax);
inputs = struct('means', varMean, 'stds', varStd, 'dists', varDist, 'g_func', g, 'N', 10000);
output = monteCarloSimulation(inputs)
output.Pf
output.Beta
It runs properly when the function 'beamUnderMovingLoad()' has only one output, but Id like to select the output in the 'g' function.
Trust all clear!

You will have to write a wrapper that can select an output for you. There is no built-in functionality to do so.
Some like this should work:
function out=output_selector(fun,k,varargin)
% Select the k-th output variable given some input.
% The first input should be a function handle. Any inputs required for the
% function can provided as extra arguments.
out = cell(1,k);
[out{:}]=fun(varargin{:});
out = out{end};
end
