Loop input variables into function to get the various output in table
显示 更早的评论
Hello!
I have a function for which i have some variables as input that create output as follows:
function(A,B,C,D,E,F,G) - So I input varibles A thru G and get the below output X thu Z
for i = 1:varout
switch i
case 1
varout{1} = X;
case 2
varout{2} = Y;
case 3
varout{3} = Z;
end
I have for example the following input variables I want to pass thru the function all at once for me to get a table with all the output variables given the input.
A B C D E F G X Y Z
1 2 1 2 6 7 1 =
3 1 1 8 7 4 10 =
1 5 1 2 6 3 8 =
Appreciate all the help in this matter! Thanks so much!

The question/goal is not clear.
I see you're using varout which suggests you expect a variable number of outputs. But you mention that the output should be a table so it's not clear how that all ties together.
Also, what are A,B,C,...,G? Could you provide examples of these inputs?
I have a feeling you're working with a variable number of inputs and want a single output variable that is a table containing the columns from your key when given the input variables. Is that right?

That's helpful. How do those inputs map onto what the outputs should be?

Where do those X,Y,Z values come from?
What should the program do?

That should be easy to implement. If those are your variable names, then that's exactly the code you would use to produce those outputs. But I must admit, I am still quite uncertain of the goal.

Something like this maybe?
% your initial table
input_table = array2table([ ...
41 62 92 17 3 7 -2; ...
41 61 92 18 4 7 -2; ...
41.5 62 92 6 3 7 -2; ...
],'VariableNames',{'A' 'B' 'C' 'D' 'E' 'F' 'G'})
% convert to a cell array
inputs = table2cell(input_table)
% pass each row of inputs to your function, and
% collect the outputs in another cell array
N = size(input_table,1);
outputs = cell(N,3);
for ii = 1:N
[outputs{ii,:}] = your_function(inputs{ii,:});
end
outputs
% convert the outputs to a table
output_table = cell2table(outputs,'VariableNames',{'X' 'Y' 'Z'})
function [X,Y,Z] = your_function(A,B,C,D,E,F,G)
X = A+B+C+D+E+F+G;
Y = X / 2;
Z = X+Y;
end
