Calculation of a sum with variable values from textbox prompt

Hi,

I'm looking to get an user input on amount of Resistors, then make an array with that number. Then make a prompt with an input for each resistor value, to be added to the array.

My concrete question is in regards to the prompting, how do i get multiple edit fields in the promt, and connect them to the array,

also accept suggestions for the summing too.

Formula i wish to calculate:

Code so far:

clc, clear, close all;


prompt = {'Enter number of resistors:'};
dlgtitle = 'Number of resistors';
dims = [1 35];
definput = {'1'};
Resistors = inputdlg(prompt,dlgtitle,dims,definput);
R_array = zeros(1,str2double(Resistors(1)))

Use the uitable component.

"how do i get multiple edit fields in the promt"

Refer to the documentation page of inputdlg on how to get multiple inputs.

You will get the inputs in the form of a cell array, manipulate them according to your requirements.

Thank you for the feedback.

I figured out a way. For reference if other people have the same, or similar question:

prompt = {'Resistors in paralell:'};
dlgtitle = 'Number of resistors';
dims = [1 35];
definput = {'1'};
Resistors = inputdlg(prompt,dlgtitle,dims,definput);
R_array = zeros(1,str2double(Resistors(1)));

for i=1:numel(R_array)
    temparr{i} = "Resistor";
end
x = inputdlg(temparr);
sum = 0;
for i=1:numel(x)
    sum = sum + (1/str2double(x{i}));
end
R_total = sum^-1

Then make a prompt with an input for each resistor value

It shouldn't require multiple prompts,

nor a loop to do the summation:

>> x=inputdlg

x =

1×1 cell array

{'[1,2,3,4]'}

>> sum(str2num(x{1}))

ans =
