How do I get a dialog box to ask for a variable from out of the workspace?

I want the dialogbox to ask for a variable. Lateron I want to use this input variable for something else.

clear all
close all
clc

S1R2  = csvimport('S1R2.csv'); %measurment position S1R2
S1R3  = csvimport('S1R3.csv'); %measurment position S1R3



prompt = {'Measurement position:','Parameter:'};
dlgtitle = 'Input';
dims = [1 40];
answer = inputdlg(prompt,dlgtitle,dims)

Q = <--- %a variable selected from the answer

T30 = Q(2:end,2); %Variable T30
T30 = cell2mat(T30);

T20 = Q(2:end,4);%Variable T20
T20 = cell2mat(T20);

I assume that you are trying to process the columns of a csv file. Here are a few pointers that may be of help

• Instead of csvimport, you may use “readtable” function to import data from a CSV file into MATLAB. The “readtable” function automatically detects the header and the number of lines to skip.

T = readtable('myfile.csv');

• Alternatively, you can specify the number of lines to skip using:

T = readtable('myfile.csv', 'HeaderLines',3);  % skips the first three rows of data

• You can use brace indexing to access the content of the "answer" variable. For instance the following syntax returns the content of the "Parameter" field

p = answer{2};
